Subject: [PATCH kernel] rcu: Fix comment for rcu_dereference_raw_notrace
Date: Mon, 2 Nov 2015 13:21:47 +1100 [thread overview]
Message-ID: <1446430907-25955-1-git-send-email-aik@ozlabs.ru> (raw)
rcu_dereference_raw() calls indirectly rcu_read_lock_held() while
rcu_dereference_raw_notrace() does not so fix the comment about the latter.
