[PATCH] mm: micro optimise zone_watermark_ok
Having min be a signed quantity means gcc can't turn high latency divides into shifts. There happen to be two such divides for GFP_ATOMIC (ie. networking, ie. important) allocations, one of which depends on the other. Fixing this makes code smaller as a bonus. Shame on somebody (probably me). Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
