The "depends_on module" pragma can be used to declare a dependency on a DTrace module, which for kernel probes corresponds to a KLD. Such dependencies cannot be checked if the KLD is compiled into the kernel. Therefore, allow a module dependency to be satisfied if either a kernel module or a KLD with the specified name is loaded.
