[GIT PULL] Followup io_uring fixes for 6.3-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Hi Linus,

Here's a set of fixes/changes that didn't make the first cut, either
because they got queued before I sent the early merge request, or fixes
that came in afterwards. In detail:

- Don't set MSG_NOSIGNAL on recv/recvmsg opcodes, as AF_PACKET will
  error out (David)

- Fix for spurious poll wakeups (me)

- Fix for a file leak for buffered reads in certain conditions (Joseph)

- Don't allow registered buffers of mixed types (Pavel)

- Improve handling of huge pages for registered buffers (Pavel)

- Provided buffer ring size calculation fix (Wojciech)

- Minor cleanups (me)

Please pull!
