This allows applications to issue async discards, rather than rely on the blocking sync ioctl discards we already have. The sync support is difficult to use outside of idle/cleanup periods. On a real (but slow) device, testing shows the following results when compared to sync discard: qd64 sync discard: 21K IOPS, lat avg 3 msec (max 21 msec) qd64 async discard: 76K IOPS, lat avg 845 usec (max 2.2 msec) qd64 sync discard: 14K IOPS, lat avg 5 msec (max 25 msec) qd64 async discard: 56K IOPS, lat avg 1153 usec (max 3.6 msec) and synthetic null_blk testing with the same queue depth and block size settings as above shows: Type Trim size IOPS Lat avg (usec) Lat Max (usec) ============================================================== sync 4k 144K 444 20314 async 4k 1353K 47 595 sync 1M 56K 1136 21031 async 1M 94K 680 760" * tag 'for-6.12/io_uring-discard-20240913' of git://git.kernel.dk/linux: block: implement async io_uring discard cmd block: introduce blk_validate_byte_range() filemap: introduce filemap_invalidate_pages io_uring/cmd: give inline space in request to cmds io_uring/cmd: expose iowq to cmds |
