e2fsck: Reduce unnecessary I/O when checking backup superblock E2fsck needs to check to see if the backup superblock differs from the primary superblock. Previously it was doing so by calling ext2fs_open(), which does a lot of unnecessary work, including reading all of the backup block group descriptors. Avoid this by reading in the backup superblock directly. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
