Definitely not. Modules in Linux are not threads, either kernel- or
fullblown. They are not scheduled but just sit around your RAM waiting
to be called into exactly like other kernel code. They _are_ exactly
like other kernel code once loaded.
When you print current from a module you're printing the task_struct of
whatever process is running inside that kernel code (at init time, the
insmod process).
