Subject: fix leaf_lookup for indirect blocks.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=e2167d0724c8d607e7627aaa0ceb77cc84642eee;p=LaFS.git

fix leaf_lookup for indirect blocks.

If the space was an exact multiple of 6 bytes, we would not consider
the final entry as a possible 'next'.
