cluster/dht: Linkfiles creation with correct uid/gid
If renames are done with different uid/gid (non-owners), then we would end up with incorrect uid/gid. The fix is to create linkfiles, and heal the uid/gid as root:root. This preserves our notion of creation as root:root and heal the uid/gid as root:root in all paths. Additionally, we need to consider uid/gid from only src_cached subvol, and not from linkfiles. rename is also done as root:root if done on linkfile, as setattr of ownership on linkfile is done after the rename Change-Id: Icb5d431dc42da9c02dfae81980e3fe769a47a274 BUG: 884597 Signed-off-by: shishir gowda <sgowda@redhat.com> Reviewed-on: http://review.gluster.org/4682 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>
