Re: [PATCH][XFRM] Replace rwlock on xfrm_policy_afinfo with rcu

xfrm_policy_afinfo is read mosly data structure.
Write on xfrm_policy_afinfo is done only at the
time of configuration.
So rwlocks can be safely replaced with RCU.

RCUs usage optimizes the performance.

This patch doesn't apply to the net-next tree, please respin.

Also:

-			xfrm_policy_afinfo[afinfo->family] = NULL;
+			rcu_assign_pointer(xfrm_policy_afinfo[afinfo->family],
+				NULL);

Indent that NULL argument properly, it must line up with the first
column after the openning '(' on the previous line.
