On i386, the user space accessor functions copy_from/to_user() both invoke might_sleep(), do a quick sanity check, and then pass the work on to their __copy_from/to_user() counterparts, which again invoke might_sleep(). Given that no actual work happens between these two calls, it is best to eliminate one of the redundant might_sleep()s.
