Is it possible for me to reproduce here? (is there a testcase or a
downloadable thing?, URL?) I never got this reports thus I wasn't aware of
any problem. (I may have missed spare reports on l-k on May due holydays)

I definitely see the race in the allocator but we can fix it right without
hurting performance significantly. And unless there's swap going on it's
unlikely to trigger due the big kernel locking all over the place.

BTW, I'd be curious if people could test such thing also in 2.2.17pre6aa2
and tell me if they can break it too.

Thanks for the info.

Andrea
