Subject: [PATCH 4/9] staging: hv: fix a kernel warning in netvsc_linkstatus_callback()
Date: Thu, 21 Jul 2011 10:14:52 -0700 [thread overview]
Message-ID: <1311268497-8671-5-git-send-email-haiyangz@microsoft.com> (raw)
In-Reply-To: <1311268497-8671-1-git-send-email-haiyangz@microsoft.com>
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.
