This commit causes ext4/028 to fail with a 1k blocksize.  The failure
happens after just under 45 minutes; before this commit, ext4/028
would complete after a second.

Do you have a preference regarding whether I just drop this commit, or
drop the whole series?  The previous patch looks fine to me and fixes
a real problem, so my plan is to keep the 1/2 commit and drop this
one.
