From 265a92856b17524c87da0258ac0d3cec80ae1d35 Mon Sep 17 00:00:00 2001 From: Alexey Kuznetsov Date: Fri, 17 Mar 2006 16:05:43 -0800 Subject: [PATCH] [NET]: Fix race condition in sk_wait_event(). It is broken, the condition is checked out of socket lock. It is wonderful the bug survived for so long time.
