| Subject: staging: hv: fix a kernel warning in netvsc_linkstatus_callback() |
| |
| From: Haiyang Zhang <haiyangz@microsoft.com> |
| |
| commit c4b6a2eaf1c14810a4803d658f68614365978738 upstream. |
| |
| netif_notify_peers() caused a kernel warning in netvsc_linkstatus_callback(), |
| because netvsc_linkstatus_callback() is within IRQ context. So we move |
| the first call to netif_notify_peers() into queued work as well, but with |
| zero delay. |
| |
| In addition to "staging-next", this should also be back-ported to stable |
| kernels 2.6.32 and later. |
