Subject: What is XFRM_POLICY_LOCALOK for?

Hello,

 I tried to understand what XFRM_POLICY_LOCALOK is for. (include/linux/xfrm.h)
It is defined thus:
 #define XFRM_POLICY_LOCALOK	1	/* Allow user to override global policy */

is it part of flags of xfrm_userpolicy_info?? I doubt this, since we have
above flags two defines:

#define XFRM_POLICY_ALLOW	0
#define XFRM_POLICY_BLOCK	1

Moreover, both XFRM_POLICY_BLOCK and XFRM_POLICY_LOCALOK has a vlaue of 1.

I could not see any usage for XFRM_POLICY_LOCALOK in kernel code.

Regards,
Ian B
