I'm not familiar with it either (had to look it up to check it's the right thing) - in mm/ we're accustomed to writing things like "(size + PAGE_CACHE_SIZE - 1) >> PAGE_CACHE_SHIFT"; but that took the line over 80 columns, and I dreaded someone somewhere mailing in to ask "Why didn't you use DIV_ROUND_UP?" ;-)
