Example:
Applying this patch to the linux kernel sources:
diff --git a/include/net/xfrm.h b/include/net/xfrm.h
index e476541..178eb50 100644
- a/include/net/xfrm.h
+ b/include/net/xfrm.h
@@ -853,7 +853,7 @@ struct xfrm_algo_comp_info {

char *name;
char *compat;
- u8 available:1;
+ u8 available;
union {
struct xfrm_algo_auth_info auth;
struct xfrm_algo_encr_info encr;
We get this result:
