H A Dpin_user_pages.rst22 ("gup") family of functions. FOLL_PIN has significant interactions and
25 FOLL_PIN is internal to gup, meaning that it should not appear at the gup call
30 FOLL_LONGTERM, on the other hand, *is* allowed to be set at the gup call sites.
39 FOLL_PIN and FOLL_GET are mutually exclusive for a given gup call. However,
53 For these pin_user_pages*() functions, FOLL_PIN is OR'd in with whatever gup
202 The whole point of marking folios as "DMA-pinned" or "gup-pinned" is to be able
214 ...is a prerequisite to solving the long-running gup+DMA problem.
