And it breaks autofs4

autofs: pipe file descriptor does not contain proper ops

this comes because the autofs4 pipe fd doesn't have a write file

Badari do you remember any place in your patches where you didn't
add do_sync_write for a file_operations instance?

Ian, what kind of file is the autofs4 pipe? is it a named pipe or
a fifo or a "real" file?

Ahh. Sorry missed the actual question.
It's a FIFO created with pipe(2).
