| OK, I'm having trouble not with your patch but the original code. This | test of map->page outside the spinlock looks like an incorrect fix to a | race. If map->page can be NULL right after we release the lock then it | can become NULL after this test just as easily. The map->page is not freed once allocated (free_pidmap() does not free the page). I guess the point is if you exceeded 32K pids (one page worth of pids) once, you would exceed it again; so no point freeing the page and reallocating the next time.
