Hi Linus,
Sending this one early as I'm out on vacation.
Here are the io_uring updates queued up for the 6.11 merge window.
Nothing major this time around, various minor improvements and
cleanups/fixes. This pull request contains:
- Add bind/listen opcodes. Main motivation is to support direct
descriptors, to avoid needing a regular fd just for doing these two
operations (Gabriel)
- Probe fixes (Gabriel)
- Treat io-wq work flags as atomics. Not fixing a real issue, but may
as well and it silences a KCSAN warning (me)
- Cleanup of rsrc __set_current_state() usage (me)
- Add 64-bit for {m,f}advise operations (me)
- Improve performance of data ring messages (me)
- Fix for ring message overflow posting (Pavel)
- Fix for freezer interaction with TWA_NOTIFY_SIGNAL. Not strictly an
io_uring thing, but since TWA_NOTIFY_SIGNAL was originally added for
faster task_work signaling for io_uring, bundling it with this pull.
(Pavel)
- Add Pavel as a co-maintainer
- Various cleanups (me, Thorsten)
Please pull!
