>From 5e60bcaa263dac8a3df4334459414bcb0808009f Mon Sep 17 00:00:00 2001 From: Steven Whitehouse <[email protected]> Date: Mon, 20 Apr 2009 08:58:45 +0100 Subject: [PATCH] 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.
