H A D | llc.h | 0dcb8225 Tue Aug 07 14:41:38 CDT 2018 Cong Wang <xiyou.wangcong@gmail.com> llc: use refcount_inc_not_zero() for llc_sap_find()
llc_sap_put() decreases the refcnt before deleting sap from the global list. Therefore, there is a chance llc_sap_find() could find a sap with zero refcnt in this global list.
Close this race condition by checking if refcnt is zero or not in llc_sap_find(), if it is zero then it is being removed so we can just treat it as gone.
