I should have referenced the sgi git tree commit:

http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs.git;a=commitdiff;h=15440319767942a363f282d6585303d3d75088ba

and should have also cc'd the xfs list, doing so now.

It should be merged there, yes.  Was hoping that sgi would request that
soon....

I was going to do it yesterday after merging in another patch series but
there was problem with one of the patches.  I'll get a pull request out
real soon.
