Subject: [PATCH v9 35/96] mm/filemap: Add folio_wait_bit
Date: Wed,  5 May 2021 16:05:27 +0100	[thread overview]
Message-ID: <20210505150628.111735-36-willy@infradead.org> (raw)
In-Reply-To: <20210505150628.111735-1-willy@infradead.org>

Rename wait_on_page_bit() to folio_wait_bit().  We must always wait on
the folio, otherwise we won't be woken up due to the tail page hashing
to a different bucket from the head page.

This commit shrinks the kernel by 691 bytes, mostly due to moving
the page waitqueue lookup into folio_wait_bit_common().
