mmap and multiple memory chucks allocated by kmalloc()

[lan mu]

Hi experts,

I have almost 620000 bytes data store in Kernal space
and would like to pass to user space via mmap.

Can I use the kmalloc to allocate 5 memory chucks
(4096*30) and then use remap_page_range() to map those
5 chucks one by one? it not seems to work. Anyone can
tell me if it's feasible? or I have to use vmalloc?

Now I only can mmaped the first chuck buffer and make
it work.

Since I'm not in the user group list, please send
directly email to me.

Thanks your help in advance!

-Lan
