but, what are the advantages of using such a technique and what is the
problem with copy_from_user? may be there could be other ways to slove
them.
I was hoping to provide a bigger stack for specific operations done on
behalf of an application (through a system call). It is part of a
research on sinking user-level code into the kernel.
There is no problem with copy_from_user when used normally. We are not
using it normally, though ;-)
