How do the kernel implement a thread group that share same memory area?
The process descriptor structure - task _struct has the field mm that is pointer to mm_stuct which has the information of the memory used by a process.
When you create a thread group that share same memory pages the mm fields of all processes point to the same mm_struct..
Hope it helps.

HelloDo kernel threads have different address space like User processes have? I mean if I allocate some memory in kernel thread A then can kernel thread B see it or can some driver see it?Thanks in advance- A
