I'm sure there is, but being a kernel person, I tend to look at things
from that end. And the memory pools there are most likely the biggest
waste of memory there. The memory also isn't swappable, though that
doesn't matter much here.

If you are referring to the patch in question, functionally there will
be no difference. It's merely fixing a misguided attempt at "optimizing"
a slow path.
I'd wager a guess that the oom killer is going to need some work
