[PATCH net, 0/2] net: Add llist_node init and fix hv_netvsc namespace error

Posted by Haiyang Zhang 2 months, 2 weeks ago

From: Haiyang Zhang <haiyangz@microsoft.com>

Add llist_node init to setup_net(), so we can check if the node is on list.
Then, fix the namespace callback function in hv_netvsc.

  hv_netvsc: Fix panic during namespace deletion with VF

Can you not do the moving from a workqueue? Schedule a work, let the
stack finish what it's doing, take rtnl_lock, do you your own moving?
