yeah, it should. For my list of on-disk structures, arm eabi structure
layout is identical to ia64 - I don't think any heads up is needed.

do you still have that small fs image? I'll take a look. There was
also an arm get_unaligned issue which hit xfs in another spot,

might be worth seeing if you still have trouble with that fix in place
(which is slated for 2.6.25)
