Both uses of find_stripe() require a fairly complicated dance to increment the reference count. Move this into a common find_get_stripe() helper. No functional changes intended.

stripe_add_to_batch_list() is better done in the loop in make_request instead of inside add_stripe_bio(). This is clearer and allows for storing the batch_head state outside the loop in a subsequent patch. The call to add_stripe_bio() in retry_aligned_read() is for read and batching only applies to write. So it's impossible for batching to happen at that call site. No functional changes intended.

There are a few uses of an ugly ternary operator in raid5_make_request() to check if a sector is a head of a reshape sector. Factor this out into a simple helper called ahead_of_reshape().

The check in raid5_make_request differs very slightly from the logic that causes it to block lower down. This likely does not cause a bug as the check is fuzzy anyway (as reshape may move on between the first check and the subsequent check). However, make it consistent so it can be cleaned up in a subsequent patch. The condition which causes the schedule is: !(mddev->reshape_backwards ? logical_sector < conf->reshape_progress : logical_sector >= conf->reshape_progress) && (mddev->reshape_backwards ? logical_sector < conf->reshape_safe : logical_sector >= conf->reshape_safe) The condition that causes the early bailout is made to match this.

Since the bug which commit 8b48ec23 ("md: don't unregister sync_thread with reconfig_mutex held") fixed is related with action_store path, other callers which reap sync_thread didn't need to be changed. Let's pull md_unregister_thread from md_reap_sync_thread, then fix previous bug with belows. 1. unlock mddev before md_reap_sync_thread in action_store. 2. save reshape_position before unlock, then restore it to ensure position not changed accidentally by others.

Boot-time assembly of arrays with md= command-line arguments breaks when CONFIG_BLOCK_LEGACY_AUTOLOAD is unset. md_setup_drive() in md-autodetect.c calls blkdev_get_by_dev(), assuming this implicitly creates the block device. Fix this by attempting to md_alloc() the array first. As in the probe path, ignore any error as failure is caught by blkdev_get_by_dev() anyway.

The mdadm test 07layouts randomly produces a kernel hung task deadlock. The deadlock is caused by the suspend_lo/suspend_hi files being set by the mdadm background process during reshape and not being cleared because the process hangs. (Leaving aside the issue of the fragility of freezing kernel tasks by buggy userspace processes...) When the background mdadm process hangs it, is waiting (without a timeout) on a change to the sync_completed file signalling that the reshape has completed. The process is woken up a couple times when the reshape finishes but it is woken up before MD_RECOVERY_RUNNING is cleared so sync_completed_show() reports 0 instead of "none". To fix this, notify the sysfs file in md_reap_sync_thread() after MD_RECOVERY_RUNNING has been cleared. This wakes up mdadm and causes it to continue and write to suspend_lo/suspend_hi to allow IO to continue.

The 07layouts test in mdadm fails on some systems. The failure presents itself as the backup file not being removed before the next layout is grown into: mdadm: /dev/md0: cannot create backup file /tmp/md-test-backup: File exists This is because the background mdadm process, which is responsible for cleaning up this backup file gets into an infinite loop waiting for the reshape to start. mdadm checks the mdstat file if a reshape is going and, if it is not, it waits for an event on the file or times out in 5 seconds. On faster machines, the reshape may complete before the 5 seconds times out, and thus the background mdadm process loops waiting for a reshape to start that has already occurred. mdadm reads the mdstat file to start, but mdstat does not report that the reshape has begun, even though it has indeed begun. So the mdstat_wait() call (in mdadm) which polls on the mdstat file won't ever return until timing out. The reason mdstat reports the reshape has started is due to an issue in status_resync(). recovery_active is subtracted from curr_resync which will result in a value of zero for the first chunk of reshaped data, and the resulting read will report no reshape in progress. To fix this, if "resync - recovery_active" is an overloaded value, force the value to be MD_RESYNC_ACTIVE so the code reports a resync in progress.

Comments in the code document special values used for mddev->curr_resync. Make this clearer by using an enum to label these values. The only functional change is a couple places use the wrong comparison operator that implied 3 is another special value. They are all fixed to imply that 3 or greater is an active resync.

The only place that uses RCU to access conf->log is in r5l_log_disk_error(). This function is mostly used in the IO path and once with mddev_lock() held in raid5_change_consistency_policy(). It is known that the IO will be suspended before the log is freed and r5l_log_exit() is called with the mddev_lock() held. This should mean that conf->log can not be freed while the function is being called, so the RCU protection is not necessary. Drop the rcu_read_lock() as well as the synchronize_rcu() and rcu_assign_pointer() usage.

The raid5-cache code relies on there being no IO in flight when log_exit() is called. There are two places where this is not guaranteed so add mddev_suspend() and mddev_resume() calls to these sites. The site in raid5_change_consistency_policy() is in the error path, and another similar call site already has suspend/resume calls just below it; so it should be equally safe to make that change here. There is one remaining site in raid5_remove_disk() that we call log_exit() without suspending the array. Unfortunately, as the comment stated, we cannot call mddev_suspend from raid5d.

We usually do all our bitmap IO in units of PAGE_SIZE. With very small or oddly sized external meta data, or with PAGE_SIZE != 4k, it can happen that our last on-disk bitmap page is not fully PAGE_SIZE aligned, so we may need to adjust the size of the IO. We used to do that with min_t(unsigned int, PAGE_SIZE, last_allowed_sector - current_offset); And for just the right diff, (unsigned int)(diff) will result in 0. A bio of length 0 will correctly be rejected with an IO error (and some scary WARN_ON_ONCE()) by the scsi layer. Do the calculation properly.

Pull io_uring buffered writes support from Jens Axboe: "This contains support for buffered writes, specifically for XFS. btrfs is in progress, will be coming in the next release. io_uring does support buffered writes on any file type, but since the buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt to do so if IOCB_NOWAIT is set, any buffered write will effectively be handled by io-wq offload. This isn't very efficient, and we even have specific code in io-wq to serialize buffered writes to the same inode to avoid further inefficiencies with thread offload. This is particularly sad since most buffered writes don't block, they simply copy data to a page and dirty it. With this pull request, we can handle buffered writes a lot more effiently. If balance_dirty_pages() needs to block, we back off on writes as indicated. This improves buffered write support by 2-3x.

This is similar to the accept (or poll) support for have for multishot, where a single SQE can trigger everytime data is received.

Pull ARM boardfile deprecation from Arnd Bergmann: "Over the past ten years, new machine support was based on device tree, and an initial set of about 400 boards using ATAGS with boardfile for booting were grandfathered in, with about half of them either removed or converted to DT over time. Based on the recent mailing list discussion I started, I have now turned the findings into a set of patches that marks most board files as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards. For the boards that are marked as unused, there are two final chances for potential users: The removal is scheduled to take place after the longterm stable kernel at the end of 2022, so users can stay on that version for another few years, and if anyone still has one of these machines and is planning to keep updating kernels beyond that version, they can speak up now to have their boards taken off the list again. Waiting for the LTS release also makes sure that there will be at least one longterm kernel that contains the recent multiplatform conversion along while still supporting all legacy boards. The short summary of the current status is: - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known users and will be removed entirely. - The mmp and davinci platforms have DT support for the important machines and will become DT-only after this. - s3c64xx, dove, orion5x, and pxa keep some board files to allow those to be migrated over to DT more easily, but most board files are getting removed now. DT support on these platforms is partially working but requires changes to additional drivers for the other boards. - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the moment but have some boards with known users. Removing the board files that nobody uses should make it easier to try a DT conversion if anyone cares. There is no explicit timeline what happens with the boards that remain after this removal, but I expect to revisit this in the future, and with most boards gone, there will be a good time to do a treewide review of platform drivers that never gained DT support and have no remaining in-tree board files" Link: https://lore.kernel.org/linux-arm-kernel/CAK8P3a0Z9vGEQbVRBo84bSyPFM-LF+hs5w8ZA51g2Z+NsdtDQA@mail.gmail.com/ * tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency ARM: iop32x: mark as unused ARM: s3c: mark most board files as unused ARM: omap1: add Kconfig dependencies for unused boards ARM: sa1100: mark most boards as unused ARM: footbridge: mark cats board for removal ARM: mmp: mark all board files for removal ARM: ep93xx: mark most board files as unused ARM: davinci: mark all ATAGS board files as unused ARM: orion: add ATAGS dependencies ARM: pxa: add Kconfig dependencies for ATAGS based boards ARM: add CONFIG_UNUSED_BOARD_FILES ARM: add ATAGS dependencies to non-DT platforms
