I would like to see SLQB merged in mainline, made default, and wait for
some number releases. Then we take what we know, and try to make an
informed decision about the best one to take. I guess that is problematic
in that the rest of the kernel is moving underneath us. Do you have
another idea?

Nope.  If it doesn't work out, we can remove it again I guess.

OK, I have these numbers to show I'm not completely off my rocker to suggest
we merge SLQB :) Given these results, how about I ask to merge SLQB as default
in linux-next, then if nothing catastrophic happens, merge it upstream in the
next merge window, then a couple of releases after that, given some time to
test and tweak SLQB, then we plan to bite the bullet and emerge with just one
main slab allocator (plus SLOB).

That's a plan.

SLQB tends to be the winner here.

Can you think of anything with which it will be the loser?
