Revision d9724772e69cb8076231202292665ca74eec13e1 authored by Or Gerlitz on 22 December 2016, 12:28:15 UTC, committed by David S. Miller on 23 December 2016, 16:59:56 UTC
When matching on flags, we should require the user to provide the mask and avoid using an all-ones mask. Not doing so causes matching on flags provided w.o mask to hit on the value being unset for all flags, which may not what the user wanted to happen.
