Pull io_uring fixes from Jens Axboe:
 "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)"
