Includes selftests. - Refactor bio integrity to support filesystem initiated integrity operations and arbitrary buffer alignment. - Clean up bio allocation, splitting bio_alloc_bioset() into clear fast and slow paths. Add bio_await() and bio_submit_or_kill() helpers, unify synchronous bi_end_io callbacks. - Fix zone write plug refcount handling and plug removal races. Add support for serializing zone writes at QD=1 for rotational zoned devices, yielding significant throughput improvements. - Add SED-OPAL ioctls for Single User Mode management and a STACK_RESET command. - Add io_uring passthrough (uring_cmd) support to the BSG layer. - Replace pp_buf in partition scanning with struct seq_buf. - zloop improvements and cleanups. - drbd genl cleanup, switching to pre_doit/post_doit. - NVMe pull request via Keith: - Fabrics authentication updates - Enhanced block queue limits support - Workqueue usage updates - A new write zeroes device quirk - Tagset cleanup fix for loop device - MD pull requests via Yu Kuai: - Fix raid5 soft lockup in retry_aligned_read() - Fix raid10 deadlock with check operation and nowait requests - Fix raid1 overlapping writes on writemostly disks - Fix sysfs deadlock on array_state=clear - Proactive RAID-5 parity building with llbitmap, with write_zeroes_unmap optimization for initial sync - Fix llbitmap barrier ordering, rdev skipping, and bitmap_ops version mismatch fallback - Fix bcache use-after-free and uninitialized closure - Validate raid5 journal metadata payload size - Various cleanups - Various other fixes, improvements, and cleanups* tag 'for-7.1/block-20260411' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (146 commits) ublk: fix tautological comparison warning in ublk_ctrl_reg_buf scsi: bsg: fix buffer overflow in scsi_bsg_uring_cmd() block: refactor blkdev_zone_mgmt_ioctl MAINTAINERS: update ublk driver maintainer email Documentation: ublk: address review comments for SHMEM_ZC docs ublk: allow buffer registration before device is started ublk: replace xarray with IDA for shmem buffer index allocation ublk: simplify PFN range loop in __ublk_ctrl_reg_buf ublk: verify all pages in multi-page bvec fall within registered range ublk: widen ublk_shmem_buf_reg.len to __u64 for 4GB buffer support xfs: use bio_await in xfs_zone_gc_reset_sync block: add a bio_submit_or_kill helper block: factor out a bio_await helper block: unify the synchronous bi_end_io callbacks xfs: fix number of GC bvecs selftests/ublk: add read-only buffer registration test selftests/ublk: add filesystem fio verify test for shmem_zc selftests/ublk: add hugetlbfs shmem_zc test for loop target selftests/ublk: add shared memory zero-copy test selftests/ublk: add UBLK_F_SHMEM_ZC support for loop target ...

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 <ushankar@purestorage.com>Reviewed-by: Ming Lei <ming.lei@redhat.com>Link: https://patch.msgid.link/20260405-cancel-v2-2-02d711e643c2@purestorage.comSigned-off-by: Jens Axboe <axboe@kernel.dk> List of files: /linux/tools/testing/selftests/ublk/test_generic_17.sh Mon, 06 Apr 2026 04:25:31 +0000 Uday Shankar <ushankar@purestorage.com>
