Subject: [GIT PULL] Final io_uring updates/fixes for 6.15-rc1
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
Hi Linus,
Final separate pull request for io_uring. Started out as a series of
cleanups improvements and improvements for registered buffers, but as
the last series of the io_uring changes for 6.15, it also collected a
few fixes for the other branches on top. Sits on top of the previously
sent out zc-rx and epoll-wait pull requests. This pull request contains:
- Add support for vectored fixed/registered buffers. Previously only
single segments have been supported for commands, now vectored
variants are supported as well. This series includes networking
and file read/write support.
- Small series unifying return codes across multi and single shot.
- Small series cleaning up registerd buffer importing.
- Adding support for vectored registered buffers for uring_cmd.
- Fix for io-wq handling of command reissue.
- Various little fixes and tweaks.
Please pull!
