#     Merge tag 'for-6.12/io_uring-discard-20240913' of git://git.kernel.dk/linux
#     
#     Pull io_uring async discard support from Jens Axboe:
#      "Sitting on top of both the 6.12 block and io_uring core branches,
#       here's support for async discard through io_uring.
#     
#       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)
#             ==============================================================
