[Tetsuo Handa]

syzbot is reporting hung task at pipe_write() [1], for mutex_lock_nested() from pipe_write() by
task-A can be blocked forever waiting for handle_userfault() from copy_page_from_iter() from
pipe_write() by task-B to complete and call mutex_unlock().

Is this a problem of fs/userfaultfd.c , for otherwise we would have to avoid page fault with
uninterruptible lock held?

By the way, who should be listed in MAINTAINERS file for userfaultfd ?
