From 49686f71060e342bce6644a5c69fbc6ad0e75a13 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 8 Jan 2007 14:31:40 +0000 Subject: [PATCH] [GFS2] Fix ordering of page disposal vs. glock_dq In case of unlinked files with dirty pages GFS2 wasn't clearing the pages in quite the right order. This patch clears the pages earlier (before the qlock_dq) to avoid the situation that the release of the glock results in attempting to write back data that has already been deallocated.
