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!
