[-- Attachment #1: sched-message.patch --]
[-- Type: text/plain, Size: 7500 bytes --]
The previous patch encourage me to go look at all the messages in
the network scheduler and fix them. Many messages were missing
any severity level. Some serious ones that should never happen
were turned into WARN(), and the random noise messages that were
handled changed to pr_debug().
