I really hate using bits for these kinds of interfaces. I'm forgetful
and never remember which bit is which, and they're possible to run out of.

I'm not saying do it now, but we can switch over to:

echo 'slab|pagecache' > drop_caches
or
echo 'quiet|slab' > drop_caches

any time we want and still have compatibility with the existing bitwise
interface.
