Subject: [PATCH] block: partition: use RCU_INIT_POINTER() for NULLing.
Date: Thu, 5 May 2016 23:24:06 +0530 [thread overview]
Message-ID: <1462470846-10446-1-git-send-email-falakreyaz@gmail.com> (raw)
It is safe to use RCU_INIT_POINTER() to NULL, instead of
rcu_assign_pointer().
This results in slightly smaller/faster code.
