2020-01-03compat_ioctl: move HDIO ioctl handling into drivers/ideArnd Bergmann5-27/+54
Most of the HDIO ioctls are only used by the obsolete drivers/ide subsystem, these can be handled by changing ide_cmd_ioctl() to be aware of compat mode and doing the correct transformations in place and using it as both native and compat handlers for all drivers. The SCSI drivers implementing the same commands are already doing this in the drivers, so the compat_blkdev_driver_ioctl() function is no longer needed now. The BLKSECTSET and HDIO_GETGEO_BIG ioctls are not implemented in any driver any more and no longer need any conversion.

2019-11-18m68k/atari: Convert Falcon IDE drivers to platform driversMichael Schmitz1-20/+40
Autoloading of Falcon IDE driver modules requires converting these drivers to platform drivers. Add platform device for Falcon IDE interface in Atari platform setup code. Use this in the pata_falcon driver in place of the simple platform device set up on the fly. Convert falconide driver to use the same platform device that is used by pata_falcon also. (With the introduction of a platform device for the Atari Falcon IDE interface, the old Falcon IDE driver no longer loads (resource already claimed by the platform device)). Tested (as built-in driver) on my Atari Falcon.

2019-10-23compat_ioctl: move tape handling into driversArnd Bergmann1-6/+21
MTIOCPOS and MTIOCGET are incompatible between 32-bit and 64-bit user space, and traditionally have been translated in fs/compat_ioctl.c. To get rid of that translation handler, move a corresponding implementation into each of the four drivers implementing those commands. The interesting part of that is now in a new linux/mtio.h header that wraps the existing uapi/linux/mtio.h header and provides an abstraction to let drivers handle both cases easily. Using an in_compat_syscall() check, the caller does not have to keep track of whether this was called through .unlocked_ioctl() or .compat_ioctl().

2019-05-09ide: officially deprecated the legacy IDE driverChristoph Hellwig1-0/+3
After a recent chat with Dave we agreed to try to finally kill off the legacy IDE code base. Set a two year grace period in which we try to move everyone over. There are a few pieces of hardware not supported by libata yet, but for many of them we aren't even sure if there are any users. For those that have users we have usually found a volunteer to add libata support. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: David S.

2019-04-12Revert "ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd"Martin Wilck3-4/+8
This reverts commit 7eec77a1816a7042591a6cbdb4820e9e7ebffe0e. Instead of leaving disk->events completely empty, we now export the supported events again, and tell the block layer not to forward events to user space by not setting DISK_EVENT_FLAG_UEVENT. This allows the block layer to distinguish between devices that for which events should be handled in kernel only, and devices which don't support any meda change events at all.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-2/+0
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

2019-01-31ide: ensure atapi sense request aren't preemptedJens Axboe4-38/+57
There's an issue with how sense requests are handled in IDE. If ide-cd encounters an error, it queues a sense request. With how IDE request handling is done, this is the next request we need to handle. But it's impossible to guarantee this, as another request could come in between the sense being queued, and ->queue_rq() being run and handling it. If that request ALSO fails, then we attempt to doubly queue the single sense request we have. Since we only support one active request at the time, defer request processing when a sense request is queued.

Pull block updates from Jens Axboe: "This is the main pull request for block/storage for 4.21. Larger than usual, it was a busy round with lots of goodies queued up. Most notable is the removal of the old IO stack, which has been a long time coming. No new features for a while, everything coming in this week has all been fixes for things that were previously merged. This contains: - Use atomic counters instead of semaphores for mtip32xx (Arnd) - Cleanup of the mtip32xx request setup (Christoph) - Fix for circular locking dependency in loop (Jan, Tetsuo) - bcache (Coly, Guoju, Shenghui) * Optimizations for writeback caching * Various fixes and improvements - nvme (Chaitanya, Christoph, Sagi, Jay, me, Keith) * host and target support for NVMe over TCP * Error log page support * Support for separate read/write/poll queues * Much improved polling * discard OOM fallback * Tracepoint improvements - lightnvm (Hans, Hua, Igor, Matias, Javier) * Igor added packed metadata to pblk. Now drives without metadata per LBA can be used as well. * Fix from Geert on uninitialized value on chunk metadata reads. * Fixes from Hans and Javier to pblk recovery and write path. * Fix from Hua Su to fix a race condition in the pblk recovery code. * Scan optimization added to pblk recovery from Zhoujie. * Small geometry cleanup from me. - Conversion of the last few drivers that used the legacy path to blk-mq (me) - Removal of legacy IO path in SCSI (me, Christoph) - Removal of legacy IO stack and schedulers (me) - Support for much better polling, now without interrupts at all. blk-mq adds support for multiple queue maps, which enables us to have a map per type. This in turn enables nvme to have separate completion queues for polling, which can then be interrupt-less. Also means we're ready for async polled IO, which is hopefully coming in the next release. - Killing of (now) unused block exports (Christoph) - Unification of the blk-rq-qos and blk-wbt wait handling (Josef) - Support for zoned testing with null_blk (Masato) - sx8 conversion to per-host tag sets (Christoph) - IO priority improvements (Damien) - mq-deadline zoned fix (Damien) - Ref count blkcg series (Dennis) - Lots of blk-mq improvements and speedups (me) - sbitmap scalability improvements (me) - Make core inflight IO accounting per-cpu (Mikulas) - Export timeout setting in sysfs (Weiping) - Cleanup the direct issue path (Jianchao) - Export blk-wbt internals in block debugfs for easier debugging (Ming) - Lots of other fixes and improvements" * tag 'for-4.21/block-20181221' of git://git.kernel.dk/linux-block: (364 commits) kyber: use sbitmap add_wait_queue/list_del wait helpers sbitmap: add helpers for add/del wait queue handling block: save irq state in blkg_lookup_create() dm: don't reuse bio for flushes nvme-pci: trace SQ status on completions nvme-rdma: implement polling queue map nvme-fabrics: allow user to pass in nr_poll_queues nvme-fabrics: allow nvmf_connect_io_queue to poll nvme-core: optionally poll sync commands block: make request_to_qc_t public nvme-tcp: fix spelling mistake "attepmpt" -> "attempt" nvme-tcp: fix endianess annotations nvmet-tcp: fix endianess annotations nvme-pci: refactor nvme_poll_irqdisable to make sparse happy nvme-pci: only set nr_maps to 2 if poll queues are supported nvmet: use a macro for default error location nvmet: fix comparison of a u16 with -1 blk-mq: enable IO poll if .nr_queues of type poll > 0 blk-mq: change blk_mq_queue_busy() to blk_mq_queue_inflight() blk-mq: skip zero-queue maps in blk_mq_map_swqueue ...
