Subject: [PATCH v3 43/59] netfs: Rearrange netfs_io_subrequest to put request pointer first
Date: Thu, 7 Dec 2023 21:21:50 +0000 [thread overview]
Message-ID: <20231207212206.1379128-44-dhowells@redhat.com> (raw)
In-Reply-To: <20231207212206.1379128-1-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.
