Summary
jbd2: remove wrong sb->s_sequence check
Details

In the Linux kernel, the following vulnerability has been resolved:

jbd2: remove wrong sb->s_sequence check

Journal emptiness is not determined by sb->ssequence == 0 but rather by sb->sstart == 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.
