Except, apparently, not, at least in my experience.

Ask the xfs guys if they see stack overflows on x86_64, or on x86.

I've personally never seen common stack problems with xfs on x86_64, but
it's very common on x86.  I don't have a great answer for why, but
that's my anecdotal evidence.

That sounds like a very good thing to collect, and maybe if I re-send a
"clearly state stack overflows at oops time" patch you can easily keep tabs.

Thanks,
