Subject: [PATCH v14 124/138] fs: Convert vfs_dedupe_file_range_compare to folios
Date: Thu, 15 Jul 2021 04:36:50 +0100	[thread overview]
Message-ID: <20210715033704.692967-125-willy@infradead.org> (raw)
In-Reply-To: <20210715033704.692967-1-willy@infradead.org>

We still only operate on a single page of data at a time due to using
kmap().  A more complex implementation would work on each page in a folio,
but it's not clear that such a complex implementation would be worthwhile.
