In the Linux kernel, the following vulnerability has been resolved:
jbd2: remove wrong sb->s_sequence check
Journal emptiness is not determined by sb->s_sequence == 0 but rather by sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a valid transaction ID so the check can spuriously trigger. Remove the invalid WARN_ON.
