Tue, 10 Feb 2026 02:57:21 +0100

Merge tag 'for-7.0/block-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linuxPull block updates from Jens Axboe: - Support for batch request processing for ublk, improving the efficiency of the kernel/ublk server communication. This can yield nice 7-12% performance improvements - Support for integrity data for ublk - Various other ublk improvements and additions, including a ton of selftests additions and updated - Move the handling of blk-crypto software fallback from below the block layer to above it. This reduces the complexity of dealing with bio splitting - Series fixing a number of potential deadlocks in blk-mq related to the queue usage counter and writeback throttling and rq-qos debugfs handling - Add an async_depth queue attribute, to resolve a performance regression that's been around for a qhilw related to the scheduler depth handling - Only use task_work for IOPOLL completions on NVMe, if it is necessary to do so. An earlier fix for an issue resulted in all these completions being punted to task_work, to guarantee that completions were only run for a given io_uring ring when it was local to that ring. With the new changes, we can detect if it's necessary to use task_work or not, and avoid it if possible. - rnbd fixes: - Fix refcount underflow in device unmap path - Handle PREFLUSH and NOUNMAP flags properly in protocol - Fix server-side bi_size for special IOs - Zero response buffer before use - Fix trace format for flags - Add .release to rnbd_dev_ktype - MD pull requests via Yu Kuai - Fix raid5_run() to return error when log_init() fails - Fix IO hang with degraded array with llbitmap - Fix percpu_ref not resurrected on suspend timeout in llbitmap - Fix GPF in write_page caused by resize race - Fix NULL pointer dereference in process_metadata_update - Fix hang when stopping arrays with metadata through dm-raid - Fix any_working flag handling in raid10_sync_request - Refactor sync/recovery code path, improve error handling for badblocks, and remove unused recovery_disabled field - Consolidate mddev boolean fields into mddev_flags - Use mempool to allocate stripe_request_ctx and make sure max_sectors is not less than io_opt in raid5 - Fix return value of mddev_trylock - Fix memory leak in raid1_run() - Add Li Nan as mdraid reviewer - Move phys_vec definitions to the kernel types, mostly in preparation for some VFIO and RDMA changes - Improve the speed for secure erase for some devices - Various little rust updates - Various other minor fixes, improvements, and cleanups* tag 'for-7.0/block-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (162 commits) blk-mq: ABI/sysfs-block: fix docs build warnings selftests: ublk: organize test directories by test ID block: decouple secure erase size limit from discard size limit block: remove redundant kill_bdev() call in set_blocksize() blk-mq: add documentation for new queue attribute async_dpeth block, bfq: convert to use request_queue->async_depth mq-deadline: covert to use request_queue->async_depth kyber: covert to use request_queue->async_depth blk-mq: add a new queue sysfs attribute async_depth blk-mq: factor out a helper blk_mq_limit_depth() blk-mq-sched: unify elevators checking for async requests block: convert nr_requests to unsigned int block: don't use strcpy to copy blockdev name blk-mq-debugfs: warn about possible deadlock blk-mq-debugfs: add missing debugfs_mutex in blk_mq_debugfs_register_hctxs() blk-mq-debugfs: remove blk_mq_debugfs_unregister_rqos() blk-mq-debugfs: make blk_mq_debugfs_register_rqos() static blk-rq-qos: fix possible debugfs_mutex deadlock blk-mq-debugfs: factor out a helper to register debugfs for all rq_qos blk-wbt: fix possible deadlock to nest pcpu_alloc_mutex under q_usage_counter ...

Thu, 08 Jan 2026 10:19:44 +0100

selftests: ublk: support non-O_DIRECT backing filesA subsequent commit will add support for using a backing file to storeintegrity data. Since integrity data is accessed in intervals ofmetadata_size, which may be much smaller than a logical block on thebacking device, direct I/O cannot be used. Add an argument tobacking_file_tgt_init() to specify the number of files to open fordirect I/O. The remaining files will use buffered I/O. For now, continueto request direct I/O for all the files.Signed-off-by: Caleb Sander Mateos Reviewed-by: Ming Lei Signed-off-by: Jens Axboe List of files: /linux/tools/testing/selftests/ublk/common.c

Merge tag 'for-6.15/io_uring-20250322' of git://git.kernel.dk/linuxPull io_uring updates from Jens Axboe: "This is the first of the io_uring pull requests for the 6.15 merge window, there will be others once the net tree has gone in. This contains: - Cleanup and unification of cancelation handling across various request types. - Improvement for bundles, supporting them both for incrementally consumed buffers, and for non-multishot requests. - Enable toggling of using iowait while waiting on io_uring events or not. Unfortunately this is still tied with CPU frequency boosting on short waits, as the scheduler side has not been very receptive to splitting the (useless) iowait stat from the cpufreq implied boost. - Add support for kbuf nodes, enabling zero-copy support for the ublk block driver. - Various cleanups for resource node handling. - Series greatly cleaning up the legacy provided (non-ring based) buffers. For years, we've been pushing the ring provided buffers as the way to go, and that is what people have been using. Reduce the complexity and code associated with legacy provided buffers. - Series cleaning up the compat handling. - Series improving and cleaning up the recvmsg/sendmsg iovec and msg handling. - Series of cleanups for io-wq. - Start adding a bunch of selftests. The liburing repository generally carries feature and regression tests for everything, but at least for ublk initially, we'll try and go the route of having it in selftests as well. We'll see how this goes, might decide to migrate more tests this way in the future. - Various little cleanups and fixes"* tag 'for-6.15/io_uring-20250322' of git://git.kernel.dk/linux: (108 commits) selftests: ublk: add stripe target selftests: ublk: simplify loop io completion selftests: ublk: enable zero copy for null target selftests: ublk: prepare for supporting stripe target selftests: ublk: move common code into common.c selftests: ublk: increase max buffer size to 1MB selftests: ublk: add single sqe allocator helper selftests: ublk: add generic_01 for verifying sequential IO order selftests: ublk: fix starting ublk device io_uring: enable toggle of iowait usage when waiting on CQEs selftests: ublk: fix write cache implementation selftests: ublk: add variable for user to not show test result selftests: ublk: don't show `modprobe` failure selftests: ublk: add one dependency header io_uring/kbuf: enable bundles for incrementally consumed buffers Revert "io_uring/rsrc: simplify the bvec iter count calculation" selftests: ublk: improve test usability selftests: ublk: add stress test for covering IO vs. killing ublk server selftests: ublk: add one stress test for covering IO vs. removing device selftests: ublk: load/unload ublk_drv when preparing & cleaning up tests ...
