Linus et al,
	Mea culpa.  The online defrag code in the ocfs2 feature pull had
a naked 64-bit divide that I missed in eyeballing and we all missed in
testing.  None of us managed to build the sucker on 32bit in the past
two months.  That's on me.  Thank you to akpm for noticing.  Also
included is a bugfix in the defrag location guessing.
	I'd really like to get this in before -rc1 so that ocfs2 builds
aren't broken there.  Please pull.
