Single physical memory location has multiple virtual addresses?



Hi,

Suppose I have a kernel module that dynamically allocates memory (via
kmalloc) for user space. Now my doubt is whether this chunk of
physical memory would have two virtual addresses?

- One virtual address that will be used by kernel to refer to the
memory (the address returned by kmalloc)

- One virtual address as will be seen by the user space application?

Is my understanding correct?

Thanks,

Dan
