[PATCH] file: Add locking to f_getown
This has been needed for a long time, but now with the advent of a reference counted struct pid there are real consequences for getting this wrong. Someone I think it was Oleg Nesterov pointed out that this construct was missing locking, when I introduced struct pid. After taking time to review the locking construct already present I figured out which lock needs to be taken. The other paths that access f_owner.pid take either the f_owner read or the write lock.
