USER_NOTIF_MAGIC is assigned to int variables in this test so set it to INT_MAX to avoid warnings:
seccomp_bpf.c: In function ‘user_notification_continue’: seccomp_bpf.c:3088:26: warning: overflow in implicit constant conversion [-Woverflow] #define USER_NOTIF_MAGIC 116983961184613L ^ seccomp_bpf.c:3572:15: note: in expansion of macro ‘USER_NOTIF_MAGIC’ resp.error = USER_NOTIF_MAGIC; ^~~~~~~~~~~~~~~~
