Hi Nic,

This patch modifies ft_prli_locked() such that the ACL list lookup only 
happens if FC_SPP_EST_IMG_PAIR has been set by the initiator. That is a 
behavior change and this has not been mentioned in the patch 
description. I think the patch description should mention that behavior 
change and also that it should explain why that behavior change is 
acceptable - if it is acceptable.

Bart.
