If RTDM was, one day, ported over something else than a Linux
kernel-space based solution (for instance, over a port of Xenomai
without Linux, or in Linux user-space), then you would not have to
change your driver codeto have it compile over that new port.
Until then, printk and rtdm_printk are identical.
Note that the first paragraph is something very hypothetical, because in
an RTDM driver, you generally have some other Linux kernel-space
specific code, such as for instance the registration as a PCI driver,
though the necessary parts of the Linux API could be implemented for
that hypothetical port. But in that case, so could printk.
So...
