Date: Mon, 11 May 2015 10:51:55 +0200 From: Nicholas Mc Guire <hofrat@...dl.org> To: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com> Cc: Josh Triplett <josh@...htriplett.org>, Steven Rostedt <rostedt@...dmis.org>, Mathieu Desnoyers <mathieu.desnoyers@...icios.com>, Lai Jiangshan <laijs@...fujitsu.com>, linux-kernel@...r.kernel.org, Nicholas Mc Guire <hofrat@...dl.org> Subject: [PATCH] rcu: change function declaration to bool rcu_cpu_has_callbacks() is declared int but is actually returning bool and all call-sites currently use it as bool so the declaration should be bool as well. Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org> --- ./kernel/rcu/tree.c:3538 WARNING: return of wrong type int != bool, as the description of rcu_cpu_has_callbacks() states: " * Return true if the specified CPU has any callback...." this probably should be a bool All (3) call sites are conditions and are treating it as boolean.
