From 140ffcec4def3ee3af7565b2cf1d3b2580f7e180 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Thu, 2 Mar 2006 02:54:28 -0800 Subject: [PATCH] [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).
