From 52fcd11c0900b0cbc584eeda12a6e27dd6c9d046 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 20 Apr 2009 08:58:45 +0100 Subject: GFS2: Clear dirty bit at end of inode glock sync The dirty bit can get set during the inode glock sync. Its too complicated to change that at the moment, so this is the quick fix - to clear the bit again at the end of the function.
