marker: optimize mq_update_dirty_inode_task
In function mq_update_dirty_inode_task we do readdirp on a dirty directory and for entry we again do lookup to fecth the contribution xattr. We can fetch this contribution as part of readdirp Change-Id: I766593c0dba793f1ab3b43625acce1c7d9af8d7f BUG: 1320818 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/13892 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Manikandan Selvaganesh <mselvaga@redhat.com>
