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.
