Looks like a fine cleanup, but I'd prefer that
#define use_lockless_fast_path() {(true)/(false)}
to look much less like it's some function call. The first read-through
it looked like some very dynamic thing to me.
Just doing
#define USE_LOCKLESS_FAST_PATH ..
would make it much more visually obvious that it's not some kind of
complex run-time decision.
