Hi Linus,
Here's a set of fixes that either weren't quite ready for the first, or came about from some intensive testing on memcached with 350K+ sockets. In particular, this pull request contains:
- Fixes for races or deadlocks around poll handling
- Don't double account fixed files against RLIMIT_NOFILE
- IORING_OP_OPENAT LFS fix
- Poll retry handling (Bijan)
- Missing finish_wait() for SQPOLL (Hillf)
- Cleanup/split of io_kiocb alloc vs ctx references (Pavel)
- Fixed file unregistration and init fixes (Xiaoguang)
- Various little fixes (Xiaoguang, Pavel, Colin)
Please pull!
