2025-05-23ublk: add feature UBLK_F_QUIESCEMing Lei
Add feature UBLK_F_QUIESCE, which adds control command `UBLK_U_CMD_QUIESCE_DEV` for quiescing device, then device state can become `UBLK_S_DEV_QUIESCED` or `UBLK_S_DEV_FAIL_IO` finally from ublk_ch_release() with ublk server cooperation. This feature can help to support to upgrade ublk server application by shutting down ublk server gracefully, meantime keep ublk block device persistent during the upgrading period. The feature is only available for UBLK_F_USER_RECOVERY.

2025-05-23traceevent/block: Add REQ_ATOMIC flag to block trace eventsRitesh Harjani (IBM)
Filesystems like XFS can implement atomic write I/O using either REQ_ATOMIC flag set in the bio or via CoW operation. It will be useful if we have a flag in trace events to distinguish between the two. This patch adds char 'U' (Untorn writes) to rwbs field of the trace events if REQ_ATOMIC flag is set in the bio. <W/ REQ_ATOMIC> ================= xfs_io-4238 [009] ..... 4148.126843: block_rq_issue: 259,0 WFSU 16384 () 768 + 32 none,0,0 [xfs_io] <idle>-0 [009] d.h1. 4148.129864: block_rq_complete: 259,0 WFSU () 768 + 32 none,0,0 [0] <W/O REQ_ATOMIC> =============== xfs_io-4237 [010] ..... 4143.325616: block_rq_issue: 259,0 WS 16384 () 768 + 32 none,0,0 [xfs_io] <idle>-0 [010] d.H1. 4143.329138: block_rq_complete: 259,0 WS () 768 + 32 none,0,0 [0] Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reviewed-by: Ojaswin Mujoo <ojaswin@linux.ibm.com> Link: https://lore.kernel.org/r/44317cb2ec4588f6a2c1501a96684e6a1196e8ba.1747921498.git.ritesh.list@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

2025-05-23fs: convert mount flags to enumStephen Brennan
In prior kernel versions (5.8-6.8), commit 9f6c61f96f2d9 ("proc/mounts: add cursor") introduced MNT_CURSOR, a flag used by readers from /proc/mounts to keep their place while reading the file. Later, commit 2eea9ce4310d8 ("mounts: keep list of mounts in an rbtree") removed this flag and its value has since been repurposed. For debuggers iterating over the list of mounts, cursors should be skipped as they are irrelevant. Detecting whether an element is a cursor can be difficult. Since the MNT_CURSOR flag is a preprocessor constant, it's not present in debuginfo, and since its value is repurposed, we cannot hard-code it. For this specific issue, cursors are possible to detect in other ways, but ideally, we would be able to read the mount flag definitions out of the debuginfo. For that reason, convert the mount flags to an enum.

2025-05-23io_uring/io-wq: only create a new worker if it can make progressJens Axboe
Hashed work is serialized by io-wq, intended to be used for cases like serializing buffered writes to a regular file, where the file system will serialize the workers anyway with a mutex or similar. Since they would be forcibly serialized and blocked, it's more efficient for io-wq to handle these individually rather than issue them in parallel. If a worker is currently handling a hashed work item and gets blocked, don't create a new worker if the next work item is also hashed and mapped to the same bucket. That new worker would not be able to make any progress anyway.

2025-05-23io_uring/io-wq: ignore non-busy worker going to sleepJens Axboe
When an io-wq worker goes to sleep, it checks if there's work to do. If there is, it'll create a new worker. But if this worker is currently idle, it'll either get woken right back up immediately, or someone else has already created the necessary worker to handle this work. Only go through the worker creation logic if the current worker is currently handling a work item. That means it's being scheduled out as part of handling that work, not just going to sleep on its own. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2025-05-23bcachefs: Path must be locked if trans->locked && should_be_lockedKent Overstreet
If path->should_be_locked is true, that means user code (of the btree API) has seen, in this transaction, something guarded by the node this path has locked, and we have to keep it locked until the end of the transaction.

2025-05-23bcachefs: Kill bch2_path_put_nokeep()Kent Overstreet
bch2_path_put_nokeep() was intended for paths we wouldn't need to preserve for a transaction restart - it always frees them right away when the ref hits 0. But since paths are shared, freeing unconditionally is a bug, the path might have been used elsewhere and have should_be_locked set, i.e. we need to keep it locked until the end of the transaction.

2025-05-23platform/x86/intel/pmc: Fix Arrow Lake U/H NPU PCI IDTodd Brandt
The ARL requires that the GMA and NPU devices both be in D3Hot in order for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition to the intel_pmc_core driver attempted to do this by switching them to D3 in the init and resume calls of the intel_pmc_core driver. The problem is the ARL-H/U have a different NPU device and thus are not being properly set and thus S0iX does not work properly in ARL-H/U. This patch creates a new ARL-H specific device id that is correct and also adds the D3 fixup to the suspend callback. This way if the PCI devies drop from D3 to D0 after resume they can be corrected for the next suspend. Thus there is no dropout in S0iX.

commit 68bfdc8dc0a1a ("drm/amd: Keep display off while going into S4") attempted to keep displays off during the S4 sequence by not resuming display IP. This however leads to hangs because DRM clients such as the console can try to access registers and cause a hang.

2025-05-22trace/io_uring: fix io_uring_local_work_run ctx documentationCaleb Sander Mateos
The comment for the tracepoint io_uring_local_work_run refers to a field "tctx" and a type "io_uring_ctx", neither of which exist. "tctx" looks to mean "ctx" and "io_uring_ctx" should be "io_ring_ctx".

UBLK_F_AUTO_BUF_REG requires that the buffer registered automatically is unregistered in same `io_ring_ctx`, so check it explicitly. Document this requirement for UBLK_F_AUTO_BUF_REG. Drop WARN_ON_ONCE() which is triggered from userspace code path.

2025-05-22spi: spi-fsl-dspi: Reset SR flags before sending a new messageLarisa Grigore
If, in a previous transfer, the controller sends more data than expected by the DSPI target, SR.RFDF (RX FIFO is not empty) will remain asserted. When flushing the FIFOs at the beginning of a new transfer (writing 1 into MCR.CLR_TXF and MCR.CLR_RXF), SR.RFDF should also be cleared. Otherwise, when running in target mode with DMA, if SR.RFDF remains asserted, the DMA callback will be fired before the controller sends any data. Take this opportunity to reset all Status Register fields.

2025-05-22spi: spi-fsl-dspi: Halt the module after a new message transferBogdan-Gabriel Roman
The XSPI mode implementation in this driver still uses the EOQ flag to signal the last word in a transmission and deassert the PCS signal. However, at speeds lower than ~200kHZ, the PCS signal seems to remain asserted even when SR[EOQF] = 1 indicates the end of a transmission. This is a problem for target devices which require the deassertation of the PCS signal between transfers. Hence, this commit 'forces' the deassertation of the PCS by stopping the module through MCR[HALT] after completing a new transfer. According to the reference manual, the module stops or transitions from the Running state to the Stopped state after the current frame, when any one of the following conditions exist: - The value of SR[EOQF] = 1. - The chip is in Debug mode and the value of MCR[FRZ] = 1. - The value of MCR[HALT] = 1. This shouldn't be done if the last transfer in the message has cs_change set.
