Subject: [PULL 12/16] migration: Introduce migrate_send_rp_message_req_pages()
Date: Mon, 26 Oct 2020 16:19:48 +0000 [thread overview]
Message-ID: <20201026161952.149188-13-dgilbert@redhat.com> (raw)
In-Reply-To: <20201026161952.149188-1-dgilbert@redhat.com>
From: Peter Xu <peterx@redhat.com>
This is another layer wrapper for sending a page request to the source VM. The
new migrate_send_rp_message_req_pages() will be used elsewhere in coming
patches.
