Yeah, it's not a hotpath. What I like primarily about this patch I
guess is that makes it more consistent how memcg entry is gated. You
don't have to remember which functions have the checks in the caller
and which have it in the function themselves. And I really hate the
static inline void foo(void)
{
if (foo_enabled())
__foo()
}
in the headerfile pattern.
