Subject: [PATCH net-next v2 0/4] net: switchdev: Avoid sleep in atomic with DSA

Hi all,

This patch series is to resolve a sleeping function called in atomic context
debug splat that we observe with DSA.

Let me know what you think, I was also wondering if we should just always
make switchdev_port_vlan_fill() set SWITCHDEV_F_DEFER, but was afraid this
could cause invalid contexts to be used for rocker, mlxsw, i40e etc.

Changes in v2:

- Make patch 3 actually build, thanks to Marcelo for reporting the
  problem

Thanks!

  net: switchdev: Prepare for deferred functions modifying objects
  net: switchdev: Add object dump deferred operation
  net: switchdev: Add switchdev_port_bridge_getlink_deferred
  net: dsa: Utilize switchdev_port_bridge_getlink_deferred()
