Hi Linus,
A few late stragglers in here. In particular:
- Validate full range for provided buffers (Bijan)
- Fix bad use of kfree() in buffer registration failure (Denis)
- Don't allow close of ring itself, it's not fully safe. Making it fully safe would require making the system call more expensive, which isn't worth it.
- Buffer selection fix
- Regression fix for O_NONBLOCK retry
- Make IORING_OP_ACCEPT honor O_NONBLOCK (Jiufei)
- Restrict opcode handling for SQ/IOPOLL (Pavel)
- io-wq work handling cleanups and improvements (Pavel, Xiaoguang)
- IOPOLL race fix (Xiaoguang)
Please pull!
