Hi, It is used to schedule a kernel thread that has "no real address space" or mm_struct. So, if we are scheduling-in the kernel thread (which has no p->mm) then its next->active_mm will be set to the prev->active_mm of the task that was scheduled-out, which will be the same as prev->mm if prev->mm != NULL.
