Subject: [PATCH v14 088/138] mm/filemap: Add filemap_get_folio
Date: Thu, 15 Jul 2021 04:36:14 +0100 [thread overview]
Message-ID: <20210715033704.692967-89-willy@infradead.org> (raw)
In-Reply-To: <20210715033704.692967-1-willy@infradead.org>
filemap_get_folio() is a replacement for find_get_page().
Turn pagecache_get_page() into a wrapper around __filemap_get_folio().
Remove find_lock_head() as this use case is now covered by
filemap_get_folio().
Reduces overall kernel size by 209 bytes. __filemap_get_folio() is
316 bytes shorter than pagecache_get_page() was, but the new
pagecache_get_page() is 99 bytes.
