cluster/afr : Change in volume heal info command
gluster volume heal <volname> info command will now also display if the files listed (in the output of the command) are in split-brain or possibly being healed. This patch also fixes build warning that occurs. Change-Id: I1fc92e62137f23b2b9ddf6e05819cee6230741d1 BUG: 1163804 Signed-off-by: Anuradha <atalur@redhat.com> Reviewed-on: http://review.gluster.org/9119 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
