Hi Linus,
io_uring updates for the 5.18-rc1 merge window. This pull request
contains:
- Fixes for current file position. Still doesn't have the f_pos_lock
sorted, but it's a step in the right direction (Dylan)
- Tracing updates (Dylan, Stefan)
- Improvements to io-wq locking (Hao)
- Improvements for provided buffers (me, Pavel)
- Support for registered file descriptors (me, Xiaoguang)
- Support for ring messages (me)
- Poll improvements (me)
- Fix for fixed buffers and non-iterator reads/writes (me
- Support for NAPI on sockets (Olivier)
- Ring quiesce improvements (Usama)
- Misc fixes (Olivier, Pavel)
Will merge cleanly. Please pull!
