From 2b018d57ff18e5405823e5cb59651a5b4d946d7b Mon Sep 17 00:00:00 2001 From: Xiaodong Xu Date: Sat, 22 Sep 2012 00:09:32 +0000 Subject: pppoe: drop PPPOX_ZOMBIEs in pppoe_release When PPPOE is running over a virtual ethernet interface (e.g., a bonding interface) and the user tries to delete the interface in case the PPPOE state is ZOMBIE, the kernel will loop forever while unregistering net_device for the reference count is not decreased to zero which should have been done with dev_put().
