A better name would be zone_is_movable(). We haven't been very
consistent about this in mmzone.h, but zone_is_foo() is pretty common.
And a neater implementation would be
return zone_idx(zone) == ZONE_MOVABLE;
All of which made me look

That seems reasonable.
I'm wondering if we can now remove the printk_sched() special-case.
iirc, that was needed because wake_up(klogd) would deadlock when called
from sched internals. B

I do think the old names were poorly chosen. Yes, we could fix them up
sometime but it's hardly a pressing issue.
