Btw,

back to the drop_caches patch. How about we hide the drop_caches
interface behind some mm debugging option in "Kernel Hacking"? Assuming
we don't need it otherwise on production kernels. Probably make it
depend on CONFIG_DEBUG_VM like CONFIG_DEBUG_VM_RB or so.

And then also add it to /proc/vmstat, in addition.
