[PATCH] out_of_memory() locking fix
I seem to have lost this read_unlock(). While we're there, let's turn that interruptible sleep unto uninterruptible, so we don't get a busywait if signal_pending(). (Again. We seem to have a habit of doing this). Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
