Well, I really don't want people to act dynamically differently depending on whether they can sleep or not. That makes static sanity-testing impossible. So I really think that the only really valid use of the above is on one single place: might_sleep(). Which right now doesn't do the "irqs_disabled()" test, but otherwise looks good. So the code should really just say if (gfp_mask & __GFP_WAIT) might_sleep(); and might_sleep() should be updated. Anybody want to try that and see whether things break horribly?
