| D | pin_user_pages.rst | 21 FOLL_PIN and FOLL_LONGTERM are flags that can be passed to the get_user_pages*()
23 interdependencies with FOLL_LONGTERM, so both are covered here.
30 FOLL_LONGTERM, on the other hand, *is* allowed to be set at the gup call sites.
32 all combinations of get*(), pin*(), FOLL_LONGTERM, and more. Also, the
47 FOLL_PIN is a prerequisite to FOLL_LONGTERM. Another way of saying that is,
48 FOLL_LONGTERM is a specific case, more restrictive case of FOLL_PIN.
125 FOLL_PIN, FOLL_GET, FOLL_LONGTERM: when to use which flags
150 FOLL_PIN | FOLL_LONGTERM
214 Another way of thinking about FOLL_GET, FOLL_PIN, and FOLL_LONGTERM
221 a "more severe" form of pinning. And finally, FOLL_LONGTERM is an even more
