From d4e0bfec9b6fbb9b58640b44e01bb74ae0d29b22 Mon Sep 17 00:00:00 2001 From: David Teigland Date: Thu, 3 Jan 2013 17:52:07 -0500 Subject: [PATCH] GFS2: fix skip unlock condition The recent commit fb6791d100d1bba20b5cdbc4912e1f7086ec60f8 included the wrong logic. The lvbptr check was incorrectly added after the patch was tested.
