Subject: Re: [PATCH net-next v3 10/18] nvme/host: Use sendmsg(MSG_SPLICE_PAGES) rather then sendpage

Meh:

                if (!sendpage_ok(page))
-                       msg.msg_flags &= ~MSG_SPLICE_PAGES,
+                       msg.msg_flags &= ~MSG_SPLICE_PAGES;
 
                bvec_set_page(&bvec, page, len, offset);
