Subject: [PATCH v2 23/36] btrfs: plumb through setting the fscrypt_info for ordered extents
Date: Tue, 10 Oct 2023 16:40:38 -0400 [thread overview]
Message-ID: <a4f6ac8c97cdab97937d4614fcba21aee9bc7621.1696970227.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1696970227.git.josef@toxicpanda.com>
We're going to be getting fscrypt_info from the extent maps, update the
helpers to take an fscrypt_info argument and use that to set the
encryption type on the ordered extent.
