Is there any particular reason to use CONFIG_SLAB rather than CONFIG_SLUB?

You are really asking for trouble to test something that almost nobody is exercising that code path very well nowadays.

Anyway, there is a patchset in -mm that might well introduce this regression that we could go to confirm it, but I kind of donât want to spend too much time on SLAB that suppose to be obsolete eventually.
