From f3bba03fd16e25a262323293e5a07dea173c89f7 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Tue, 11 Jul 2006 09:50:54 -0400 Subject: [PATCH] [GFS2] Fix deadlock in memory allocation We must not call GFP_KERNEL memory allocations while we are holding the log lock (read or write) since that may trigger a log flush resulting in a deadlock. Eventually we need to fix the locking in log.c, for now this solves the problem at the expense of freeing up memory as fast as we would like to. This needs to be revisited later on.
