Hi Linus,
As mentioned, here are the followup changes for io_uring. This branch
only exists to avoid the poll related conflicts that would've otherwise
arised without the split.
This pull request contains:
- Misc fixes (me, Lin)
- Series from Pavel extending the single task exclusive ring mode,
yielding nice improvements for the common case of having a single ring
per thread (Pavel)
- Cleanup for MSG_RING, removing our IOPOLL hack (Pavel)
- Further poll cleanups and fixes (Pavel)
- Misc cleanups and fixes (Pavel)
Please pull!
