void dlog (  const char *  fmt,   ... )

Logs data. This function is compatible with printk. In fact it currently sends all output to vprintk, after sending "STP: ". This allows us to easily detect SystemTap output in the log file. Parameters: fmt  A variable number of args. Bug: Lines are limited in length by printk buffer. Todo: Needs replaced with something much faster that does not use the system log.
