From 15bd50ad82a6d3421af1abe82e2554898abc4141 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Thu, 20 Dec 2012 13:21:07 -0500 Subject: GFS2: Stop looking for free blocks at end of rgrp This patch adds a return code check after calling function gfs2_rbm_from_block while determining the free extent size. That way, when the end of an rgrp is reached, it won't try to process unaligned blocks after the end.
