In preparation to drop the similar helper that sets d_op at lookup time,
add a version to set the right d_op filesystem-wide, through sb->s_d_op.
The operations structures are shared across filesystems supporting
fscrypt and/or casefolding, therefore we can keep it in common libfs
code.

In preparation to get case-insensitive dentry operations from sb->s_d_op
again, use the same structure with and without fscrypt.

When a key is added, existing directory dentries in the
DCACHE_NOKEY_NAME form are moved by the VFS to the plaintext version.
But, since they have the DCACHE_OP_REVALIDATE flag set, revalidation
will be done at each lookup only to return immediately, since plaintext
dentries can't go stale until eviction. This patch optimizes this case,
by dropping the flag once the nokey_name dentry becomes plain-text.
Note that non-directory dentries are not moved this way, so they won't
be affected.
Of course, this can only be done if fscrypt is the only thing requiring
revalidation for a dentry. For this reason, we only disable
d_revalidate if the .d_revalidate hook is fscrypt_d_revalidate itself.
It is safe to do it here because when moving the dentry to the
plain-text version, we are holding the d_lock. We might race with a
concurrent RCU lookup but this is harmless because, at worst, we will
get an extra d_revalidate on the keyed dentry, which will still find the
dentry to be valid.
Finally, now that we do more than just clear the DCACHE_NOKEY_NAME in
fscrypt_handle_d_move, skip it entirely for plaintext dentries, to avoid
extra costs.

Unencrypted and encrypted-dentries where the key is available don't need
to be revalidated by fscrypt, since they don't go stale from under VFS
and the key cannot be removed for the encrypted case without evicting
the dentry. Disable their d_revalidate hook on the first lookup, to
avoid repeated revalidation later. This is done in preparation to always
configuring d_op through sb->s_d_op.
The only part detail is that, since the filesystem might have other
features that require revalidation, we only apply this optimization if
the d_revalidate handler is fscrypt_d_revalidate itself.
Finally, we need to clean the dentry->flags even for unencrypted
dentries, so the ->d_lock might be acquired even for them. In order to
avoid doing it for filesystems that don't care about fscrypt at all, we
peek ->d_flags without the lock at first, and only acquire it if we
actually need to write the flag.

Both fscrypt_prepare_lookup_partial and fscrypt_prepare_lookup will set
DCACHE_NOKEY_NAME for dentries when the key is not available. Extract
out a helper to set this flag in a single place, in preparation to also
add the optimization that will disable ->d_revalidate if possible.

overlayfs relies on the filesystem setting DCACHE_OP_HASH or
DCACHE_OP_COMPARE to reject mounting over case-insensitive directories.
Since commit bb9cd9106b22 ("fscrypt: Have filesystems handle their
d_ops"), we set ->d_op through a hook in ->d_lookup, which
means the root dentry won't have them, causing the mount to accidentally
succeed.
In v6.7-rc7, the following sequence will succeed to mount, but any
dentry other than the root dentry will be a "weird" dentry to ovl and
fail with EREMOTE.
mkfs.ext4 -O casefold lower.img
mount -O loop lower.img lower
mount -t overlay -o lowerdir=lower,upperdir=upper,workdir=work ovl /mnt
Mounting on a subdirectory fails, as expected, because DCACHE_OP_HASH
and DCACHE_OP_COMPARE are properly set by ->lookup.
Fix by explicitly rejecting superblocks that allow case-insensitive
dentries. Yes, this will be solved when we move d_op configuration back
to ->s_d_op. Yet, we better have an explicit fix to avoid messing up
again.
While there, re-sort the entries to have more descriptive error messages
first.

Casefolded comparisons are (obviously) way more costly than a simple
memcmp. Try the case-sensitive comparison first, falling-back to the
case-insensitive lookup only when needed. This allows any exact-match
lookup to complete without having to walk the utf8 trie.
Note that, for strict mode, generic_ci_d_compare used to reject an
invalid UTF-8 string, which would now be considered valid if it
exact-matches the disk-name. But, if that is the case, the filesystem
is corrupt. More than that, it really doesn't matter in practice,
because the name-under-lookup will have already been rejected by
generic_ci_d_hash and we won't even get here.
The memcmp is safe under RCU because we are operating on str/len instead
of dentry->d_name directly, and the caller guarantees their consistency
between each other in __d_lookup_rcu_op_compare.

Pull firewire updates from Takashi Sakamoto:
"This includes the series of changes related to device attributes, as
well as slight code refactoring.
Some old devices are recognized to have legacy layout of configuration
ROM. They have an inconvenience that FireWire subsystem adds no
attributes for vendor information to corresponding devices. The main
purpose of this update is to rectify the inconvenience.
We have a slight concern about regression. The update changes the
value of modalias for the unit devices by populating its model field,
which was previously left as zero in the case. I've assessed the
potential impact of this change and anticipate it to have minimal
concern for both the kernel and user lands. The change is enough
acceptable"

Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, an assortment of updates and cleanups to many
others, and first part of the big rework of the core GPIOLIB that's
currently underway.
Add to that some code shrink in the character device module and
updates to DT bindings and that's pretty much it.
Core GPIOLIB:
- protect the global list of GPIO devices with a read-write semaphore
as it is rarely modified but can be traversed by multiple readers
at once
- remove GPIO devices from the global list when they are
*unregistered* and not when they are *released* (which only happens
when the last reference is dropped) as this may lead to a
successful lookup of an unregistered device
- remove the unnecessary "extra_checks" switch
- rename functions that are called with a lock taken
- remove duplicate includes
Character device handling:
- use locking guards to reduce the code size
- allocate the big linereq structure using the more suitable
kvzalloc()
- redulce the size of critical sections
- improve documentation
- move the debounce_period_us field out of struct gpio_desc
New drivers:
- Nuvoton NPCM SGPIO driver for BMC NPCM7xx/NPCM8xx
- Realtek DHC (Digital Home Center) SoC GPIO driver
Driver improvements:
- replace gpiochip_is_requested() with a safer alternative in the
form of gpiochip_dup_line_label() as the former returns a pointer
to a string that can be deleted
- implement the dbg_show() callback in gpio-sim
- improve the coding style for local variables by removing
unnecessary tabs
- use generic device properties instead of OF variants in gpio-mmio
- use the preferred coding style for __free() in gpio-mockup
- reuse PM ops from the gpio-tangier in gpio-elkhartlake
- rework PM and use cleanup helpers in gpio-tangier
- fix the EIC configuration in gpio-pmic-eic-sprd
- remove the unneeded call to platform_set_drvdata() in gpio-sifive
- use generic GPIO helpers for driver callbacks in gpio-dwapb
- add clock support on certain pins of gpio-ixp4xx
- don't use the core-specific DEBUG_GPIO switch in drivers
- kerneldoc improvements
DT bindings:
- add bindings for the new Realtek and Nuvoton devices
- allow gpio-ranges in gpio-dwapb
- support GPIO hogs in gpio-rockchip
- describe the label property in gpio-zynqmp-modepin
Other:
- header cleanups
- forward declarations cleanups"

Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.

It's not easy to let go responsibility for a subsystem that one cared
for for a long time, but Thierry realized that his heart isn't in the
pwm framework any more.
Thierry cared for the pwm subsystem (commit 200efedd8766 ("pwm: Take
over maintainership of the PWM subsystem")) as a maintainer during
nearly 12 years. A big thanks for the time, effort and dedication spend
during that time.
Uwe takes over maintenance.

From looking at the PCI IDs, every device supported by intelfb is
also supported by i915. Anyone still using intelfb should please
move on to i915, which does everything intelfb does but better.
Removing intelfb is motivated by the driver's excessive use of the
global screen_info state. The state belongs to architecture and
firmware code; device drivers should not attempt to access it. But
fixing intelfb would require a significant change in the driver's
probing logic. As intelfb has been obsolete for nearly 2 decades,
it is probably not worth the effort. Let's just remove it. Also
remove the related documentation.

Replace use of screen_info state with the correct interfaces from
the aperture helpers. The state is only for architecture and firmware
code. It is not guaranteed to contain valid data. Drivers are thus
not allowed to use it.
For removing conflicting firmware framebuffers, there are aperture
helpers. Hence replace screen_info with the correct functions that will
remove conflicting framebuffers for the hypervfb driver. For GEN1 PCI
devices, the driver reads the framebuffer base and size from the PCI
BAR, and uses the range for removing the firmware framebuffer. For
GEN2 VMBUS devices no range can be detected, so the driver clears all
firmware framebuffers.

When built-in, the sis driver tries to detect the current display mode
from the global screen_info state. That state is only for architecture
and firmware code. Drivers should not use it directly as it's not
guaranteed to contain valid information.
Remove the mode-detection code from sis. Drivers that want to detect a
pre-set mode on probe should read the hardware registers directly.

Allocate stifb's instance of fb_info with framebuffer_alloc(). This
is the preferred way of creating fb_info with associated driver data
stored in struct fb_info.par. Requires several, but minor, changes
through out the driver's code.
The intended side effect of this patch is that the new instance of
struct fb_info now has its device field correctly set to the parent
device of the STI ROM. A later patch can detect if the device is the
firmware's primary output. It is also now correctly located within
the Linux device hierarchy.

Store the ROM's parent device in each STI struct, so we can associate
the STI framebuffer with a device.
The new field will eventually replace the fbdev subsystem's info field,
which the function fb_is_primary_device() currently requires to detect
the firmware's output. By using the device instead of the framebuffer
info, a later patch can generalize the helper for use in non-fbdev code.

When framebuffer gets closed, the queued deferred IO gets cancelled. This
can cause some last display data to vanish. This is problematic for users
who send a still image to the framebuffer, then close the file: the image
may never appear.
To ensure none of display data get lost, flush the queued deferred IO
first before closing.
Another possible solution is to delete the cancel_delayed_work_sync()
instead. The difference is that the display may appear some time after
closing. However, the clearing of page mapping after this needs to be
removed too, because the page mapping is used by the deferred work. It is
not completely obvious whether it is okay to not clear the page mapping.
For a patch intended for stable trees, go with the simple and obvious
solution.

The driver's fsync() is supposed to flush any pending operation to
hardware. It is implemented in this driver by cancelling the queued
deferred IO first, then schedule it for "immediate execution" by calling
schedule_delayed_work() again with delay=0. However, setting delay=0
only means the work is scheduled immediately, it does not mean the work
is executed immediately. There is no guarantee that the work is finished
after schedule_delayed_work() returns. After this driver's fsync()
returns, there can still be pending work. Furthermore, if close() is
called by users immediately after fsync(), the pending work gets
cancelled and fsync() may do nothing.
To ensure that the deferred IO completes, use flush_delayed_work()
instead. Write operations to this driver either write to the device
directly, or invoke schedule_delayed_work(); so by flushing the
workqueue, it can be guaranteed that all previous writes make it to the
device.

We have managed to ascertain that all users of the old FBDEV
code that are out of tree are now gone.
The new DRM driver can be found in drivers/gpu/drm/pl111/.
The remaining out of tree user was the ARM FVP emulation
platform, running Android. Thanks to changes in Android
versions 13 and 14, Android can now use the DRM driver when
being emulated under FVP. Some final patches are being put
in place to make it fully featured.
This is essentially a revert of the partial revert in
commit 112c35237c72 ("Partially revert "video: fbdev: amba-clcd: Retire elder CLCD driver"")

which are minor, while several bug fixes on error handlers and
compression flows are good to improve the overall stability.
Enhancements:
- enable checkpoint=disable for zoned block device
- sysfs entries such as discard status, discard_io_aware, dir_level
- tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(),
f2fs_new_inode()
- use shared inode lock during f2fs_fiemap() and f2fs_seek_block()
Bug fixes:
- address some power-cut recovery issues on zoned block device
- handle errors and logics on do_garbage_collect(),
f2fs_reserve_new_block(), f2fs_move_file_range(),
f2fs_recover_xattr_data()
- don't set FI_PREALLOCATED_ALL for partial write
- fix to update iostat correctly in f2fs_filemap_fault()
- fix to wait on block writeback for post_read case
- fix to tag gcing flag on page during block migration
- restrict max filesize for 16K f2fs
- fix to avoid dirent corruption
