Pull io_uring fixes from Jens Axboe:
 "Fix for an issue reported where reading fdinfo could find a NULL
  thread as we didn't properly synchronize, and then a disable for the
  IOCB_DIO_CALLER_COMP optimization as a recent reported highlighted how
  that could lead to deadlocks if the task issued async O_DIRECT writes
  and then proceeded to do sync fallocate() calls"
