Subject: [PATCH v4 01/13] netfs: Rearrange netfs_io_subrequest to put request pointer first
Date: Wed, 13 Dec 2023 15:41:27 +0000 [thread overview]
Message-ID: <20231213154139.432922-2-dhowells@redhat.com> (raw)
In-Reply-To: <20231213154139.432922-1-dhowells@redhat.com>
Rearrange the netfs_io_subrequest struct to put the netfs_io_request
pointer (rreq) first. This then allows netfs_io_subrequest to be put in a
union with a pointer to a wrapper around netfs_io_request for cifs.
