sys_landlock_add_rule(int ruleset_fd, enum landlock_rule_type rule_type, const void *rule_attr, __u32 flags)

register	value
`r12`	445, the syscall number
`r5`	int ruleset_fd
`r6`	enum landlock_rule_type rule_type
`r7`	const void *rule_attr
`r8`	__u32 flags
`r3`	the return value

Then run brki r14,8 to enter the kernel.
