commit 8e5bfda2ffd80ebfcdc00cadd503bfcfd5422276
Author: Bob Peterson <rpeterso@redhat.com>
Date: Wed Aug 18 13:26:10 2010 -0500
fsck.gfs2 segfaults if journals are missing
This patch makes it possible for fsck.gfs2 to detect missing and damaged
journals and recreate them. Previous versions of fsck.gfs2 would
segfault if journals were missing because it made assumptions about
the jindex file pointing to a valid dinode. Also, I moved function
ji_update which was exclusively used by fsck.gfs2 from libgfs2 to fsck.
