Linux 7.1 merges block subsystem and IO_uring updates. Block changes include shared memory zero-copy I/O support for ublk (bypassing kernel/user-space per-I/O copies), file-system initiated integrity operations, SED-OPAL ioctls, IO_uring pass-through for the BSG layer, and DRBD driver cleanup. NVMe gains enhanced block queue limits, a new write zeroes device quirk, and updated Fabrics authentication. The MD Soft RAID code fixes a RAID5 soft lock-up, a potential RAID10 deadlock, and RAID1 overlapping write issues. IO_uring updates bring custom event loop logic, expanded IOPOLL capabilities, timeout improvements, zero-copy receive (ZCRX) updates, and various optimizations.
