> There are two problematic situations. > > A deadlock can happen when is_percpu is false because it can get > interrupted while holding the spinlock. Then it executes > ovs_flow_stats_update() in softirq context which tries to get > the same lock. > > The second sitation is that when is_percpu is true, the code > correctly disables BH only for the local CPU, but that confuses > lockdep enough to trigger the warning below. > > This patch disables BH for both cases fixing the real deadlock > and the lockdep warning message. ... > Signed-off-by: Flavio Leitner <f...@redhat.com> I'll let Jesse review and pick this up. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
