Subject: [GIT PULL] io_uring fixes for 5.5-rc4
Date: Thu, 26 Dec 2019 11:21:51 -0700
Message-ID: <> (raw)

Hi Linus,

This pull request:

- Removal of now unused busy wqe list (Hillf)

- Add cond_resched() to io-wq work processing (Hillf)

- And then the series that I hinted at from last week, which removes the
  sqe from the io_kiocb and keeps all sqe handling on the prep side.
  This guarantees that an opcode can't do the wrong thing and read the
  sqe more than once. This is unchanged from last week, no issues have
  been observed with this in testing. Hence I really think we should
  fold this into 5.5.

Please pull!
