Subject: [PATCH] mac802154: fix NOHZ local_softirq_pending 08 warning
Date: Wed, 2 Jan 2013 12:01:10 +0100 [thread overview]
Message-ID: <1357124470-2375-1-git-send-email-alex.aring@gmail.com> (raw)
When using nanosleep() in an userspace application we get a
ratelimit warning
NOHZ: local_softirq_pending 08
for 10 times.
This patch replaces netif_rx() with netif_rx_ni() which has
to be used from process/softirq context.
The process/softirq context will be called from fakelb driver.
See linux-kernel commit 481a819 for similar fix.
