Subject: [PATCH v2 34/34] fs/binfmt_elf: convert put_page() to put_user_page*()
From: Ira Weiny <ira.weiny@...el.com>
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").
get_dump_page calls get_user_page so put_user_page must be used
to match.
