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).
