17 # start bit by bit to force wiping of stale blocks near the end of the
18 # log. Check the block after the log ends to check for corruption
21 # - given we're only touching a single inode, the block after the
22 # log which is in the middle ag should never be touched.
23 # if it changes, we assume the log is writing over it
