We would like to writev() the whole outgoing message, but this is hard given the current need to prepend the locally-constructed xsd_sockmsg. Instead, have the caller provide xsd_sockmsg in iovec[0]. This in turn drops the 't' and 'type' parameters from xs_talkv(). Note that xs_talkv() may alter the iovec structure. This may happen when writev() is really used under the covers, and it's preferable to having the lower levels need to duplicate the iovec to edit it upon encountering a short write. xs_directory_part() is the only function impacted by this, and it's easy to rearrange to be compatible. No functional change. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Reviewed-by: Juergen Gross <jgross@suse.com> Reviewed-by: Jason Andryuk <jason.andryuk@amd.com>
