2025-01-10loop: remove the use_dio field in struct loop_deviceChristoph Hellwig
This field duplicate the LO_FLAGS_DIRECT_IO flag in lo_flags. Remove it to have a single source of truth about using direct I/O. Signed-off-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20250110073750.1582447-9-hch@lst.de Signed-off-by: Jens Axboe <axboe@kernel.dk>
2025-01-10loop: don't freeze the queue in loop_update_dioChristoph Hellwig
All callers of loop_update_dio except for loop_configure already have the queue frozen, and loop_configure works on an unbound device. Remove the superfluous recursive freezing in loop_update_dio and add asserts for the locking and freezing state instead.

2025-01-10loop: allow loop_set_status to re-enable direct I/OChristoph Hellwig
Unlike all other calls of (__)loop_update_dio, loop_set_status never looks at the O_DIRECT flag of the backing file, and thus doesn't re-enable direct I/O on an O_DIRECT backing file if e.g. the new block size would allow it. Fix that and remove the need for the separate __loop_update_dio flag.

2025-01-10loop: open code the direct I/O flag update in loop_set_dioChristoph Hellwig
loop_set_dio is different from the other (__)loop_update_dio callers in that it doesn't take any implicit conditions into account and wants to update the direct I/O flag to the user passed in value and fail if that can't be done. Open code the logic here to prepare for simplifying the other direct I/O flag updates and to make the error handling less convoluted.

2025-01-10loop: only write back pagecache when starting to to use direct I/OChristoph Hellwig
There is no point in doing an fdatasync to write out pages when switching away from direct I/O, as there won't be any. The writeback is only needed when switching to direct I/O, which would have to invalidate the pagecache less efficiently from the I/O path.

2025-01-10loop: move updating lo_flags out of loop_set_status_from_infoChristoph Hellwig
While loop_configure simplify assigns the flags passed in by userspace, loop_set_status only looks at the two changeable flags, and currently has to do a complicate dance to implement that. Move assign lo->lo_flags out of loop_set_status_from_info into the callers and thus drastically simplify the lo_flags handling in loop_set_status.

2025-01-10drm/ttm: Handle cgroup based eviction in TTMMaarten Lankhorst
cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.

2025-01-09net: ethernet: ti: cpsw_ale: Fix cpsw_ale_get_field()Sudheer Kumar Doredla
CPSW ALE has 75-bit ALE entries stored across three 32-bit words. The cpsw_ale_get_field() and cpsw_ale_set_field() functions support ALE field entries spanning up to two words at the most. The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as expected when ALE field spanned across word1 and word2, but fails when ALE field spanned across word2 and word3. For example, while reading the ALE field spanned across word2 and word3 (i.e. bits 62 to 64), the word3 data shifted to an incorrect position due to the index becoming zero while flipping. The same issue occurred when setting an ALE entry. This issue has not been seen in practice but will be an issue in the future if the driver supports accessing ALE fields spanning word2 and word3 Fix the methods to handle getting/setting fields spanning up to two words.

2025-01-09scsi: core: Fix command pass through retry regressionMike Christie
scsi_check_passthrough() is always called, but it doesn't check for if a command completed successfully. As a result, if a command was successful and the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted to retry, we will end up retrying the command. This will cause delays during device discovery because of the command being sent multiple times. For some USB devices it can also cause the wrong device size to be used. This patch adds a check for if the command was successful. If it is we return immediately instead of trying to match a failure.
