Well, I cannot really expect people to port patches to SLQB until it's
in mainline. And whether SQLB will replace SLUB remains to be seen.
We're still fixing minor issues here and there in SLUB so I have no
reason to expect SLQB stabilization to happen overnight which means
we're going to have SLUB in the tree for a while anyway.
