From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Zijlstra Subject: [PATCH v4 10/27] rcu: Mark rcu_dynticks_curr_cpu_in_eqs() inline Date: Fri, 21 Feb 2020 14:34:26 +0100 Message-ID: <20200221134215.616973418@infradead.org> References: <20200221133416.777099322@infradead.org> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Return-path: Received: from merlin.infradead.org ([205.233.59.134]:45626 "EHLO merlin.infradead.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1728910AbgBUNuq (ORCPT ); Fri, 21 Feb 2020 08:50:46 -0500 Sender: linux-arch-owner@vger.kernel.org List-ID: To: linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, rostedt@goodmis.org Cc: peterz@infradead.org, mingo@kernel.org, joel@joelfernandes.org, gregkh@linuxfoundation.org, gustavo@embeddedor.com, tglx@linutronix.de, paulmck@kernel.org, josh@joshtriplett.org, mathieu.desnoyers@efficios.com, jiangshanlai@gmail.com, luto@kernel.org, tony.luck@intel.com, frederic@kernel.org, dan.carpenter@oracle.com, mhiramat@kernel.org Since rcu_is_watching() is notrace (and needs to be, as it can be called from the tracers), make sure everything it in turn calls is notrace too. To that effect, mark rcu_dynticks_curr_cpu_in_eqs() inline, which implies notrace, as the function is tiny. Signed-off-by: Peter Zijlstra (Intel) Reviewed-by: Paul E.
