Re: 2.6.22 -mm merge plans: slub

Given the current state and the current rate of development I'd expect slub

Its developer does show signs of being active!

This is a bit unusual but there is of course some self-interest here: the
patch dependencies are getting awful and having this hanging around
out-of-tree will make 2.6.23 development harder for everyone.

That is a very strong argument: a somewhat worrisome argument,
but a very strong one.  Maintaining your sanity is important.

So on balance, given that we _do_ expect slub to have a future, I'm
inclined to crash ahead with it.  The worst that can happen will be a later
rm mm/slub.c which would be pretty simple to do.

Okay.  And there's been no chorus to echo my concern.

But if Linus' tree is to be better than a warehouse to avoid
awkward merges, I still think we want it to default to on for
all the architectures, and for most if not all -rcs.

otoh I could do some frantic patch mangling and make it easier to carry
slub out-of-tree, but do we gain much from that?

No, keep away from that.
