Bob Peterson cd928d387b gfs2: check for empty rgrp tree in gfs2_ri_update ... commit 778721510e upstream. If gfs2 tries to mount a (corrupt) file system that has no resource groups it still tries to set preferences on the first one, which causes a kernel null pointer dereference. This patch adds a check to function gfs2_ri_update so this condition is detected and reported back as an error.
