Subject: [PATCH v14 020/138] mm/filemap: Add __folio_lock_async()
Date: Thu, 15 Jul 2021 04:35:06 +0100	[thread overview]
Message-ID: <20210715033704.692967-21-willy@infradead.org> (raw)
In-Reply-To: <20210715033704.692967-1-willy@infradead.org>

There aren't any actual callers of lock_page_async(), so remove it.
Convert filemap_update_page() to call __folio_lock_async().

__folio_lock_async() is 21 bytes smaller than __lock_page_async(),
but the real savings come from using a folio in filemap_update_page(),
shrinking it from 515 bytes to 404 bytes, saving 110 bytes.  The text
shrinks by 132 bytes in total.
