E2fsck could to do more damage to a filesystem by trying to relocate inode tables due to corrupted block group descriptors, and the relocation could seriously damage the filesystem. This patch enhances ext2fs_check_desk() so it detects more self-inconsistent block group descriptors, including the cases where e2sck might be tempted to relocate the inode table, and reports the block group descriptors as invalid; this will cause e2fsck to attempt to use the backup superblocks, which hopefully have not been trashed.
