Subject: [PATCH net 0/4] hv_netvsc: fixes for VF removal path
Date: Thu, 11 Aug 2016 12:58:53 +0200	[thread overview]
Message-ID: <1470913137-29167-1-git-send-email-vkuznets@redhat.com> (raw)

Kernel crash is reported after VF is removed and detached from netvsc
device. My investigation led me to PATCH2 of this series but PATCH1 is
required to support the change. I also noticed a couple of other issues
while debugging and I fix them with PATCH3 and PATCH4.

Please review.

Vitaly Kuznetsov (4):
  hv_netvsc: don't lose VF information
  hv_netvsc: reset vf_inject on VF removal
  hv_netvsc: protect module refcount by checking
    net_device_ctx->vf_netdev
  hv_netvsc: avoid deadlocks between rtnl lock and
    netvsc_inject_disable()
