| H A D | ublk.rst | 28 ublk block device (``/dev/ublkb*``) is added by ublk driver. Any IO request
37 After the IO is handled by userspace, the result is committed back to the
38 driver, thus completing the request cycle. This way, any specific IO handling
39 logic is totally done by userspace, such as loop's IO handling, NBD's IO
40 communication, or qcow2's IO mapping.
44 IO too, which is 1:1 mapped with IO of ``/dev/ublkb*``.
46 Both the IO request forward and IO handling result committing are done via
49 give better IOPS than block IO; which is why ublk is one of high performance
50 implementation of userspace block device: not only IO request communication is
51 done by io_uring, but also the preferred IO handling in ublk server is io_uring
