[v8,01/15] mm: rename is_pinnable_pages to is_longterm_pinnable_pages

Commit Message

Sierra Guiza, Alejandro (Alex) July 7, 2022, 7:03 p.m. UTC

is_pinnable_page() and folio_is_pinnable() were renamed to
is_longterm_pinnable_page() and folio_is_longterm_pinnable()
respectively. These functions are used in the FOLL_LONGTERM flag
context.
