From a44d6aad2ce6b6707eae5683923779c34d0aa10f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 24 Sep 2016 23:29:51 +0200 Subject: [PATCH] Fix build warning in kernel/cpuset.c BugLink: http://bugs.launchpad.net/bugs/1629386 > 2 ../kernel/cpuset.c:2101:11: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] > 1 ../kernel/cpuset.c:2101:2: warning: initialization from incompatible pointer type > 1 ../kernel/cpuset.c:2101:2: warning: (near initialization for 'cpuset_cgrp_subsys.fork') This got introduced by 06ec7a1d7646 ("cpuset: make sure new tasks conform to the current config of the cpuset"). In the upstream kernel, the function prototype was changed as of b53202e63089 ("cgroup: kill cgrp_ss_priv[CGROUP_CANFORK_COUNT] and friends"). That patch is not suitable for stable kernels, and fortunately the warning seems harmless as the prototypes only differ in the second argument that is unused. Adding that argument gets rid of the warning: Signed-off-by: Greg Kroah-Hartman Signed-off-by: Tim Gardner --- kernel/cpuset.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/cpuset.c b/kernel/cpuset.c index 7b6ada28df7a..a874497ec4fd 100644 --- a/kernel/cpuset.c +++ b/kernel/cpuset.c @@ -2079,7 +2079,7 @@ static void cpuset_bind(struct cgroup_subsys_state *root_css) * which could have been changed by cpuset just after it inherits the * state from the parent and before it sits on the cgroup's task list. */ -void cpuset_fork(struct task_struct *task) +void cpuset_fork(struct task_struct *task, void *priv) { if (task_css_is_root(task, cpuset_cgrp_id)) return; -- 2.39.5
