[Ocfs2-devel] [PATCH 08/15] ocfs2: fix wake_up in unlock_ast

[Sunil Mushran]

From: David Teigland <teigland at redhat.com>

Mainline commit 07f9eebcdfaeefc8f807fa1bcce1d7c3ae6661b1

In ocfs2_unlock_ast(), call wake_up() on lockres before releasing
the spin lock on it.  As soon as the spin lock is released, the
lockres can be freed.
