Subject: [PATCH] staging/rdma/hfi1: use RCU_INIT_POINTER() when NULLing.
Date: Sun, 1 May 2016 18:05:31 +0530 [thread overview]
Message-ID: <1462106131-9073-1-git-send-email-falakreyaz@gmail.com> (raw)
It is safe to use RCU_INIT_POINTER() to NULL a pointer, instead of
rcu_assign_pointer().
This results in slightly smaller/faster code.
