From c4b6a2eaf1c14810a4803d658f68614365978738 Mon Sep 17 00:00:00 2001 From: Haiyang Zhang Date: Thu, 1 Sep 2011 12:19:42 -0700 Subject: [PATCH] staging: hv: fix a kernel warning in netvsc_linkstatus_callback() 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.
