io_uring: no read/write-retry on -EAGAIN error and O_NONBLOCK marked file
Actually two things that need fixing up here: - The io_rw_reissue() -EAGAIN retry is explicit to block devices and regular files, so don't ever attempt to do that on other types of files. - If we hit -EAGAIN on a nonblock marked file, don't arm poll handler for it. It should just complete with -EAGAIN. Cc: stable@vger.kernel.org Reported-by:Norman Maurer <norman.maurer@googlemail.com> Signed-off-by:
