marker: fix log when loc.parent and inode gfid is NULL
This patch does the following 1) Set loc.parent if it is NULL Don't log warning in txn if parent is NULL 2) Don't initiate txn when inode gfid is NULL 3) optimize invoking dirty txn with status flag Change-Id: I67dd9e6268014b0b257c136e951e6ded0a2e911f BUG: 1251454 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11863 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
