Subject: [PATCH][next] xfrm: optimise xfrm_policy_lookup_bytype
Date: Sat, 9 May 2015 19:17:37 +0800 [thread overview]
Message-ID: <1431170257-18242-1-git-send-email-roy.qing.li@gmail.com> (raw)
From: Li RongQing <roy.qing.li@gmail.com>
It is unnecessary to continue to loop the policy if the priority
of current looped police is larger than priority which is from
the policy_bydst list.
