From 43f5efc5b59db1b66e39fe9fdfc4ba6a27152afa Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 23 Mar 2010 10:10:00 +1100 Subject: [PATCH] xfs: factor log item initialisation Each log item type does manual initialisation of the log item. Delayed logging introduces new fields that need initialisation, so factor all the open coded initialisation into a common function first.
