kernel thread lives in kernel space and just access kernel space (very
likely). And since kernel space is mapped accross all processes....I
can say...or may I say, I speculate...kernel thread A will see what B
has allocated. Bottom line is, since kernel thread is the kernel
itself, thus it can access every part of the kernel freely and in the
same address space.
