Channels are a concept similar to job types. Callers must specify a channel name when queueing a new job. A list of channels is also specified when dequeueing a job. The dequeued job's channel will always be from one of the specified channel. Of course, the job types are also respected. The dequeued job will also always be from one of the specified type. Currently, all calls to jobqueue were changed so all queue operations use an empty channel name and all dequeue operations use a list containing an empty channel. Thus, this is a non-functional change. Signed-off-by: Ondřej Budai <ondrej@budai.cz>
