I've bisected through Linus' tree more than once - ISTR that there was
some special funkiness in dealing with trying to bisect through linux-next
because the tree gets redone every night.

If it *was* as easy as Linus's tree to bisect, I'd go ahead and do it.

Wow. I never *thought* to look for it there, and neither did my userspace :)
