struct timespec is not y2038 safe. Even though timespec might be
sufficient to represent timeouts, use struct timespec64 here as the plan
is to get rid of all timespec reference in the kernel.
The patch transitions the common functions: poll_select_set_timeout()
and select_estimate_accuracy() to use timespec64. And, all the syscalls
that use these functions are transitioned in the same patch.
The restart block parameters for poll uses monotonic time. Use
timespec64 here as well to assign timeout value. This parameter in the
restart block need not change because this only holds the monotonic
timestamp at which timeout should occur. And, unsigned long data type
should be big enough for this timestamp.
The system call interfaces will be handled in a separate series.
Compat interfaces need not change as timespec64 is an alias to struct
timespec on a 64 bit system.

timespec64_add_safe() has been defined in time64.h for 64 bit systems.
But, 32 bit systems only have an extern function prototype defined.
Provide a definition for the above function.
The function will be necessary as part of y2038 changes. struct
timespec is not y2038 safe. All references to timespec will be replaced
by struct timespec64. The function is meant to be a replacement for
timespec_add_safe().
The implementation is similar to timespec_add_safe().

Inotify instance is destroyed when all references to it are dropped.
That not only means that the corresponding file descriptor needs to be
closed but also that all corresponding instance marks are freed (as each
mark holds a reference to the inotify instance). However marks are
freed only after SRCU period ends which can take some time and thus if
user rapidly creates and frees inotify instances, number of existing
inotify instances can exceed max_user_instances limit although from user
point of view there is always at most one existing instance. Thus
inotify_init() returns EMFILE error which is hard to justify from user
point of view. This problem is exposed by LTP inotify06 testcase on
some machines.
We fix the problem by making sure all group marks are properly freed
while destroying inotify instance. We wait for SRCU period to end in
that path anyway since we have to make sure there is no event being
added to the instance while we are tearing down the instance. So it
takes only some plumbing to allow for marks to be destroyed in that path
as well and not from a dedicated work item.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"This includes two new updates for the ftrace infrastructure.
- With the changing of the code for filtering events by pid, from a
list of pids to a bitmask, we can now easily implement following
forks. With a new tracing option "event-fork" which, when set,
will have tasks with pids in set_event_pid, when they fork, to have
their child pids added to set_event_pid and the child will be
traced as well.
Note, if "event-fork" is set and a task with its pid in
set_event_pid exits, its pid will be removed from set_event_pid
- The addition of Tom Zanussi's hist triggers. This includes a very
thorough documentatino on how to use the hist triggers with events.
This introduces a quick and easy way to get histogram data from
events and their fields.
Some other cleanups and updates were added as well. Like Masami
Hiramatsu added test cases for the event trigger and hist triggers.
Also I added a speed up of filtering by using a temp buffer when
filters are set"

Pull ARM 64-bit DT updates from Arnd Bergmann:
"We continue ramping up platform support for 64-bit ARM machines, with
111 individual non-merge changesets touching 21 platforms.
The LG1312 platform is completely new and is the first ARM platform by
LG that we support in the mainline kernel. Two other SoCs got added
that are updated versions of existing SoC families, so the port mainly
consists of new dts files:
- The Hisilicon Hip06/D03 is the latest server platform from
Huawei/Hisilicon, and follows the Hip05/D02 platform.
- Rockchip RK3399 follows the 32-bit RK3288 that is popular in
low-end Chromebooks and the 64-bit RK3368 that is mainly found in
chinese Android TV boxes.
The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a
long-awaited overhaul with a lot of devices enabled in the DT, so it
should be much more usable with a mainline kernel now. See also

platforms, while other drivers are added for v4.7 as well, or come in
a later release.
- The Aspeed platform is probably the most interesting one, this is
what most whitebox servers use as their baseboard management
controller. We get support for the very common ast2400 and ast2500
SoCs. The OpenBMC project focuses on this chip, and the LWN
article about their ELC 2016 presentation at
https://lwn.net/Articles/683320/
triggered the submission, but the code comes from IBM's OpenPOWER
team rather than the team at Facebook. There are still a lot more
drivers that need to get added over time, and I hope both teams can
work together on that.
- OXNAS is an old platform for Network Attached Storage devices from
Oxford Semiconductor. There are models with ARM10 (!) and
ARM11MPCore cores, but for now, we only support the original ARM9
based versions. The product lineup was subsequently part of PLX,
Avago and now the new Broadcom Ltd.
https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
has some more information.
- V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
cores and is related to the existing Realview / Versatile Express
lineup, but without MMU.
We now support various NOMMU platforms, so adding a new one is
fairly straightforward.
http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
has detailed information about the platform.
Other noteworthy updates:
- Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain
Lemieux are now maintaining the platform.
This is an older ARM9 based platform from NXP (not Freescale), but
it remains in use in embedded markets.
- Kevin Hilman is now co-maintaining the Amlogic Meson platform for
both 32-bit and 64-bit ARM, and started contributing some patches.
- As is often the case, work on the OMAP platforms makes up the bulk
of the actual SoC code changes in arch/arm, but there isn't a lot
of that either"

My laptop that uses the intel 7680 iwlwifi module would no longer
connects to the network. It would fail with a "Microcode SW error
detected." and spew out register state over and over again without ever
connecting to the network.
The cause is mis-merge in commit 909b27f70643, where David seems to have
lost some of the changes to iwl_mvm_set_tx_cmd() from commit
5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU
len").
The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi:
mvm: add support for new TX CMD API"), which touched a line adjacent to
the changes in 909b27f70643.
David missed the fact that "info->driver_data[0]" had become
"skb_info->driver_data[0]". Then he removed the skb_info because it was
unused.
This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

xfs: concurrent readdir hangs on data buffer locks
Revert "btrfs: switch to ->iterate_shared()"
|

There's a three-process deadlock involving shared/exclusive barriers
and inverted lock orders in the directory readdir implementation.
It's a pre-existing problem with lock ordering, exposed by the
VFS parallelisation code.
process 1 process 2 process 3
--------- --------- ---------
readdir
iolock(shared)
get_leaf_dents
iterate entries
ilock(shared)
map, lock and read buffer
iunlock(shared)
process entries in buffer
.....
readdir
iolock(shared)
get_leaf_dents
iterate entries
ilock(shared)
map, lock buffer
<blocks>
finish ->iterate_shared
file_accessed()
->update_time
start transaction
ilock(excl)
<blocks>
.....
finishes processing buffer
get next buffer
ilock(shared)
<blocks>
And that's the deadlock.
Fix this by dropping the current buffer lock in process 1 before
trying to map the next buffer. This means we keep the lock order of
ilock -> buffer lock intact and hence will allow process 3 to make
progress and drop it's ilock(shared) once it is done.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages.
This means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than (as we
did before) try to emulate it by switching the line to an input to
get high impedance.
This is also documented throughly in Documentation/gpio/driver.txt
for those of you who did not understand one word of what I just
wrote.
- Start to do away with the unnecessarily complex and unitelligible
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another
evolutional artifact from the time when the GPIO subsystem was
unmaintained.
Archs can now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs ACKed
the changes immediately so these are included in this pull request.
- Advancing the use of the data pointer inside the GPIO device for
storing driver data by switching the PowerPC, Super-H Unicore and
a few other subarches or subsystem drivers in ALSA SoC, Input,
serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the GPIO
lines, so that each GPIO descriptor knows - if this callback is
implemented - whether the line is input or output. This also
reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names, from
the device tree. (Platform data has been supported for a while).
I bet we will get a similar mechanism for ACPI one of those days.
This makes is possible to get sensible producer names for e.g.
GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and now
also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain and in some
cases open source.
- Implement the .get_direction() callback for a few more drivers like
PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized those
who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where they
belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less"

The btrfs_{set,remove}xattr inode operations check for a read-only root
(btrfs_root_readonly) before calling into generic_{set,remove}xattr. If
this check is moved into __btrfs_setxattr, we can get rid of
btrfs_{set,remove}xattr.
This patch applies to mainline, I would like to keep it together with
the other xattr cleanups if possible, though. Could you please review?

Ubifs internally uses special inodes for storing xattrs. Those inodes
had NULL {get,set,remove}xattr inode operations before this change, so
xattr operations on them would fail. The super block's s_xattr field
would also apply to those special inodes. However, the inodes are not
visible outside of ubifs, and so no xattr operations will ever be
carried out on them anyway.

Pull block driver updates from Jens Axboe:
"On top of the core pull request, this is the drivers pull request for
this merge window. This contains:
- Switch drivers to the new write back cache API, and kill off the
flush flags. From me.
- Kill the discard support for the STEC pci-e flash driver. It's
trivially broken, and apparently unmaintained, so it's safer to
just remove it. From Jeff Moyer.
- A set of lightnvm updates from the usual suspects (Matias/Javier,
and Simon), and fixes from Arnd, Jeff Mahoney, Sagi, and Wenwei
Tao.
- A set of updates for NVMe:
- Turn the controller state management into a proper state
machine. From Christoph.
- Shuffling of code in preparation for NVMe-over-fabrics, also
from Christoph.
- Cleanup of the command prep part from Ming Lin.
- Rewrite of the discard support from Ming Lin.
- Deadlock fix for namespace removal from Ming Lin.
- Use the now exported blk-mq tag helper for IO termination.
From Sagi.
- Various little fixes from Christoph, Guilherme, Keith, Ming
Lin, Wang Sheng-Hui.
- Convert mtip32xx to use the now exported blk-mq tag iter function,
from Keith"

Pull core block layer updates from Jens Axboe:
"This is the core block IO changes for this merge window. Nothing
earth shattering in here, it's mostly just fixes. In detail:
- Fix for a long standing issue where wrong ordering in blk-mq caused
order_to_size() to spew a warning. From Bart.
- Async discard support from Christoph. Basically just splitting our
sync interface into a submit + wait part.
- Add a cleaner interface for flagging whether a device has a write
back cache or not. We've previously overloaded blk_queue_flush()
with this, but let's make it more explicit. Drivers cleaned up and
updated in the drivers pull request. From me.
- Fix for a double check for whether IO accounting is enabled or not.
From Michael Callahan.
- Fix for the async discard from Mike Snitzer, reinstating the early
EOPNOTSUPP return if the device doesn't support discards.
- Also from Mike, export bio_inc_remaining() so dm can drop it's
private copy of it.
- From Ming Lin, add support for passing in an offset for request
payloads.
- Tag function export from Sagi, which will be used in NVMe in the
drivers pull.
- Two blktrace related fixes from Shaohua.
- Propagate NOMERGE flag when making a request from a bio, also from
Shaohua.
- An optimization to not parse cgroup paths in blk-throttle, if we
don't need to. From Shaohua"

directories
Wrong return code was being returned on SMB3 rmdir of
non-empty directory.
For SMB3 (unlike for cifs), we attempt to delete a directory by
set of delete on close flag on the open. Windows clients set
this flag via a set info (SET_FILE_DISPOSITION to set this flag)
which properly checks if the directory is empty.
With this patch on smb3 mounts we correctly return
"DIRECTORY NOT EMPTY"
on attempts to remove a non-empty directory.
