-Subject: [PATCH 090/104] Adjust to recent user page API changes
-
-4.6.0 basically renamed get_user_pages() to get_user_pages_remote() and
-introduced a new get_user_pages() that always works on the current
-task.[1] Distinguish the two APIs based on kernel version we're
-compiling for.
-
-Also, there seems to have been a massive cleansing of
-page_cache_release(page) in favour of put_page(page)[2] which was an
-alias for put_page(page)[3] since 2.6.0. Before that beginning with
-2.4.0 both page_cache_release(page) and put_page(page) have been aliases
-for __free_page(page). So using put_page() instead of
-page_cache_release(page) will produce identical code for anything after
-2.4.0.
