xs_daemon_tdb() in xs_lib.c is no longer used at all, so it can be removed. xs_domain_dev() and xs_write_all() are not used by xenstored, so they can be moved to tools/libs/store/xs.c. xs_daemon_rootdir() is used by xenstored only and it only calls xs_daemon_rundir(), so replace its use cases with xs_daemon_rundir() and remove it from xs_lib.c. xs_daemon_socket_ro() is needed in libxenstore only, so move it to tools/libs/store/xs.c. Move functions used by xenstore-client only to xenstore_client.c. Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Julien Grall <jgrall@amazon.com>
