copy_from/to_user pitfalls

Hi,

I am new in kernel land. Hopefully you could
provide some information or helpful links.

It's a rather naive question:
What things to keep in mind when accessing user space
from kernel space for reading/writing data.

I know one, that a process may get blocked and its pages be out of
memory. I would like to know more (or in detail about this one too).

thanks,
-Sam
