btw., here's my SLOB wishlist:
- would be nice to have DEBUG_SLOB - people want to debug their memory
allocations, no matter which allocator they use.
- would be nice to have CONFIG_SLOB_INFO, to have /proc/slabinfo for
those who are ready to pay the .text price for it - this is nice for
memory leak debugging, etc. [should be /proc/slabinfo, not
/proc/slobinfo - to stay compatible with things like slabtop]

I have a patch somewhere for that.

Might make more sense to use my /proc/kmalloc patch for this.
