Tue, 21 Apr 2026 22:09:01 +0200

selftests: ublk: add ublk auto integrity testThe end-to-end integrity ublk selftest test_integrity_02 requires arelatively recent fio version to support I/O with integrity buffers. Adda version test_integrity_03 that uses the block layer's auto integritypath instead. The auto integrity code doesn't check the application tag,and doesn't indicate the bad guard/ref tag (just returns EILSEQ). Butit's a good smoke-test of the ublk integrity code and provides coverageof the auto integrity path as well.Signed-off-by: Caleb Sander Mateos Reviewed-by: Ming Lei Link: https://patch.msgid.link/20260421200901.1528842-4-csander@purestorage.comSigned-off-by: Jens Axboe List of files: /linux/tools/testing/selftests/ublk/Makefile

Tue, 31 Mar 2026 17:32:01 +0200

selftests/ublk: add read-only buffer registration testAdd --rdonly_shmem_buf option to kublk that registers shared memorybuffers with UBLK_SHMEM_BUF_READ_ONLY (read-only pinning withoutFOLL_WRITE) and mmaps with PROT_READ only.Add test_shmemzc_04.sh which exercises the new flag with a null target,hugetlbfs buffer, and write workload. Write I/O works because theserver only reads from the shared buffer — the data flows from clientto kernel to the shared pages, and the server reads them out.Signed-off-by: Ming Lei Link: https://patch.msgid.link/20260331153207.3635125-11-ming.lei@redhat.comSigned-off-by: Jens Axboe List of files: /linux/tools/testing/selftests/ublk/Makefile

selftests/ublk: add filesystem fio verify test for shmem_zcAdd test_shmemzc_03.sh which exercises shmem_zc through the fullfilesystem stack: mkfs ext4 on the ublk device, mount it, then runfio verify on a file inside the filesystem with --mem=mmaphuge.Extend _mkfs_mount_test() to accept an optional command that runsbetween mount and umount. The function cd's into the mount directoryso the command can use relative file paths.

Mon, 06 Apr 2026 06:25:31 +0200

selftests: ublk: test that teardown after incomplete recovery completesBefore the fix, teardown of a ublk server that was attempting to recovera device, but died when it had submitted a nonempty proper subset of thefetch commands to any queue would loop forever. Add a test to verifythat, after the fix, teardown completes. This is done by:- Adding a new argument to the fault_inject target that causes it die after fetching a nonempty proper subset of the IOs to a queue- Using that argument in a new test while trying to recover an already-created device- Attempting to delete the ublk device at the end of the test; this hangs forever if teardown from the fault-injected ublk server never completed.It was manually verified that the test passes with the fix and hangswithout it.Signed-off-by: Uday Shankar Reviewed-by: Ming Lei Link: https://patch.msgid.link/20260405-cancel-v2-2-02d711e643c2@purestorage.comSigned-off-by: Jens Axboe List of files: /linux/tools/testing/selftests/ublk/Makefile

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 ...
