Thanks for the pointer to the fix! Does that mean that the workaround
is to increase the kmemleak pool size? I had been using the default
(16000) and it seems surprising that that it wasn't enough to even get
the kernel through a standard boot sequence. Should we perhaps
increase the default mempool size?
