If you're debugging new kernel code and you realize that excessive amount
of memory is being consumed so that nothing can even fork, you may want to
try cat /proc/slabinfo before you get into that condition the next time
around, although I already suspect that you know the cache you're leaking.
It doesn't mean we need to add hundreds of lines of code to the kernel.
Try kmemleak.
