45 # create a new FS, mostly fill the log. Then wrap the log back to the
46 # start bit by bit to force wiping of stale blocks near the end of the
47 # log. Check the block after the log ends to check for corruption
50 # - given we're only touching a single inode, the block after the
51 # log which is in the middle ag should never be touched.
52 # if it changes, we assume the log is writing over it
