From f6ce5cca74b8681fdf1d7307edc66a7213b43f6f Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Thu, 22 Nov 2007 21:19:39 +0100 Subject: [PATCH] plip: use netif_rx_ni() for packet receive netif_rx is meant to be called from interrupts because it doesn't wake up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists. This fixes plip to use netif_rx_ni. It fixes the infamous error "NOHZ: local_softirq_panding 08" that happens on some machines with NOHZ and plip --- it is caused by the fact that softirq is pending and ksoftirqd is sleeping.
