This patch hard locks on my 2-way 64-bit x86 machine (sysrq doesn't

At that point we take the listlock and then the slab lock which is a
lock inversion if we do not use a trylock here. Crap.
Hmmm.. The code already goes to the next slab if an earlier one is
already locked. So I do not see how the large partial lists could be
generated.
