Do you know what the status is of your XFS patch to make it work on
ARM (old ABI)?

Excellent news,
http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs-2.6.git;a=commit;h=7a9ba9bb899933293604a2b3c5ca4f40ad5a92a8
This fixes the issue, and should be pushed in the next kernel.org xfs.
Cheers,

Please note that the above patch isn't helpful on armel.
We had some very fruitful discussions about armel w/ some XFS guys,
and it turns out that a simple patch like the attached is needed. This
works fine for me on 2.6.25-rc6, but I assume it will be made to
look/behave differently before being

Yep. Padding rules on old-ABI ARM systems are 'special', but still

said that this was a known issue. I cannot find the workaround you

Eric mentioned a workaround for this miscompilation. Do you know more
about this? Also, do you have any idea whether this issue has
actually been reported to the GCC folks?
