You know better than anyone if what I just said makes sense, so I´ll leave the ultimate decision to you :)

Hm, I've forgotten that there are kernels without the drop caches
interface. I've just checked and the first version with it is 3.9.
That's old enough for me to no longer care, at least wrt testing stuff
with i-g-t. If anyone wants to regression test such old kernels they
can pick an older version of igt.
