At the simplest level there is pr_debug() which replaces the
usual "print if DEBUG is defined" that lots of people use.
For device drivers we have something similar in dev_vdbg() et
al.
For bitmask based enabling yes it would be nice if there were
something more. But you can also get this behavior by using
DEBUG, the above interfaces, and adjusting the kernel log level
to suit what you're trying to view.
