From 3fa4cc9c2df37b393b968dcc3bb2ab1e2ff7ea7f Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 14 Dec 2015 11:24:06 -0500 Subject: [PATCH] net, cgroup: cgroup_sk_updat_lock was missing initializer bd1060a1d671 ("sock, cgroup: add sock->sk_cgroup") added global spinlock cgroup_sk_update_lock but erroneously skipped initializer leading to uninitialized spinlock warning. Fix it by using DEFINE_SPINLOCK(). Signed-off-by: Tejun Heo Reported-by: Dexuan Cui Fixes: bd1060a1d671 ("sock, cgroup: add sock->sk_cgroup") Signed-off-by: David S.
