Subject: devirtualize kernel access to DAX v2
Date: Wed, 15 Dec 2021 09:45:04 +0100 [thread overview]
Message-ID: <20211215084508.435401-1-hch@lst.de> (raw)
Hi Dan,
this series cleans up a few loose end ends and then removes the
copy_from_iter and copy_to_iter dax_operations methods in favor of
straight calls.
Changes since v1:
- reword a 'no check' comment
- clean up the flags for the copy routine variants
- drop the last patch
