    ext4: add more mount time checks of the superblock · bfe0a5f4
    Theodore Ts'o authored
    The kernel's ext4 mount-time checks were more permissive than
    e2fsprogs's libext2fs checks when opening a file system.  The
    superblock is considered too insane for debugfs or e2fsck to operate
    on it, the kernel has no business trying to mount it.
    
    This will make file system fuzzing tools work harder, but the failure
    cases that they find will be more useful and be easier to evaluate.
