[PATCH] tmpfs 4/5 three trivia

[Hugh Dickins]

tmpfs contributes to the AltSysRqM swapcache add and delete
statistics, but not to its find statistics: use lookup_swap_cache
wrapper to find_get_page, to contribute to those statistics too.
Elsewhere, use existing info pointer and NAME_MAX definition.
