The introduction of the SLUB allocator was 2.6.22, but I can't help you
bisect because I don't recall that it worked ever (?)
It _appears_ to work well with 2.6.32 Debian though...
It does indeed. slabinfo -v (run from an init=/bin/sh shell) does not
crash, nor does it report anything fishy. This kernel even survives
running e2fsck.
Output of slabinfo -l and slabinfo -T attached for both, FWIW.
I'll bisect this if I've got a bit of time, unless someone else beats me
to it.
Cheers,
