Subject: [PATCH v9 88/96] iomap: Use folio offsets instead of page offsets
Date: Wed, 5 May 2021 16:06:20 +0100 [thread overview]
Message-ID: <20210505150628.111735-89-willy@infradead.org> (raw)
In-Reply-To: <20210505150628.111735-1-willy@infradead.org>
Pass a folio around instead of the page, and make sure the offset
is relative to the start of the folio instead of the start of a page.
Also use size_t for offset & length to make it clear that these are byte
counts, and to support >2GB folios in the future.
