[GIT PULL] Block fixes for 7.1-rc3

[GIT PULL] Block fixes for 7.1-rc3

[Jens Axboe]

Hi Linus,

A few fixes for block that should go into the current kernel release.
These are mostly ublk related, in detail:

- Fix for ublk not doing an actual issue from the task_work fallback
  path. Any request hitting that should be canceled automatically.

- Fix for uring_cmd prep side handling, for the block side uring_cmd
  discard handling.

- Fix for missing validation of the io and physical block size shifts.

- Fix for a use-after-free in ublk's cancel command handling.

Please pull!
