In include/net/xfrm.h we find :
#ifdef CONFIG_XFRM_MIGRATE
extern int km_migrate(struct xfrm_selector *sel, u8 dir, u8 type,
struct xfrm_migrate *m, int num_bundles);
...
#endif
We can also guard the function body itself in net/xfrm/xfrm_state.c
with same condition.
(Problem spoted by sparse checker)
make C=2 net/xfrm/xfrm_state.o
...
net/xfrm/xfrm_state.c:1765:5: warning: symbol 'km_migrate' was not declared.
Should it be static?
