swp_swapcount	How many references to @entry are currently swapped out?* This considers COUNT_CONTINUED so it returns exact answer.
add_swap_count_continuation	add_swap_count_continuation - called when a swap count is duplicated* beyond SWAP_MAP_MAX, it allocates a new page and links that to the entry's* page of the original vmalloc'ed swap_map, to hold the continuation count
swap_count_continued	swap_count_continued - when the original swap_map count is incremented* from SWAP_MAP_MAX, check if there is already a continuation page to carry* into, carry if so, or else fail until a new continuation page is allocated;* when the original swap_map

remove_arg_zero	Arguments are '\0' separated strings found at the location bprm->p* points to; chop off the first by relocating brpm->p to right after* the first '\0' encountered.
