Do not allow directory creations without gfids as after the directories are created, operations on them fail anyway. So it is better to fail mkdir. >BUG: 1317361 >Change-Id: I8f8e3b38bbded1960b7215bac0432500f7e78038 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Reviewed-on: http://review.gluster.org/13690 >Smoke: Gluster Build System <jenkins@build.gluster.com> >Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >(cherry picked from commit b246b07896fefb261c9fb07f3f29f0d03b81b88d) Change-Id: Ibf9c84add7265e3e1755a37958e1de38307624b2 BUG: 1332372 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14188 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
