From 87affd08bc9c741b99053cabb908cf54a135a0fa Mon Sep 17 00:00:00 2001 From: Barry Naujok Date: Tue, 3 Jun 2008 11:59:18 +1000 Subject: [PATCH] [XFS] Zero uninitialised xfs_da_args structure in xfs_dir2.c Fixes a problem in the xfs_dir2_remove and xfs_dir2_replace paths which intenally call directory format specific lookup funtions that assume args->cmpresult is zeroed.
