[v3,28/41] mm/gup_benchmark.c: convert put_page() to put_user_page*()

Commit Message

[e-mail] Aug. 7, 2019, 1:33 a.m. UTC

From: John Hubbard <[e-mail]>

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or
release_pages().

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
