Message-Id: <1400274296-14765-1-git-send-email-vyasevic@redhat.com> Date: Fri, 16 May 2014 17:04:52 -0400 From: Vlad Yasevich <vyasevic@...hat.com> To: netdev@...r.kernel.org Cc: dingtianhong@...wei.com, kaber@...sh.net, vfalico@...il.com, jiri@...nulli.us, Vlad Yasevich <vyasevic@...hat.com> Subject: [PATCH v3 0/4] Fix lockdep issues with stacked devices Recent commit dc8eaaa006350d24030502a4521542e74b5cb39f vlan: Fix lockdep warning when vlan dev handle notification attempted to solve lockdep issues with vlans where multiple vlans were stacked. However, the code does not work correctly when the vlan stack is interspersed with other devices in between the vlans. Additionally, similar lockdep issues show up with other devices. This series provides a generic way to solve these issue for any devices that can be stacked. It also addresses the concern for vlan and macvlan devices. I am not sure whether it makes sense to do so for other types like team, vxlan, and bond. Thanks -vlad Since v2: - Remove rcu variants from patch1, since that function is called only under rtnl. - Fix whitespace problems reported by checkpatch Since v1: - Fixed up a goofed-up rebase. * is_vlan_dev() should be bool and that change belongs in patch3. * patch4 should not have any vlan changes in it.
