Hi Linus,
Here are the io_uring changes scheduled for this merge window. This pull
request contains:
- Support for prioritized work completions (Hao)
- Simplification of reissue (Pavel)
- Add support for CQE skip (Pavel)
- Memory leak fix going to 5.15-stable (Pavel)
- Re-write of internal poll. This both cleans up that code, and gets us
ready to fix the POLLFREE issue (Pavel)
- Various cleanups (GuoYong, Pavel, Hao)
You'll hit a trivial merge conflict pulling this due to a function name
change in 5.16-late.
Please pull!
