[PATCH 0/2] usbnet: Fix 2 problems in usbnet_stop()

From: Eugene Shatokhin
Date: Mon Aug 24 2015 - 16:14:33 EST

The following problems found when investigating races in usbnet module
are fixed here:

1. EVENT_NO_RUNTIME_PM bit of dev->flags should be read before it is
cleared by "dev->flags = 0". Thanks to Oliver Neukum for spotting this
problem and providing a fix.

2. A race on on skb_queue between usbnet_stop() and usbnet_bh().

Compared to the combined patch I sent earlier
("[PATCH] usbnet: Fix two races between usbnet_stop() and the BH"), this
patch set has the following changes:

* The fix for handling of EVENT_NO_RUNTIME_PM is now in a separate patch.
* The fix for the race on dev->flags has been removed because the race is
not considered harmful.
