    I am trying to use the function copy_to_user but after I do
    make bzImage

    I get a link error:

    kernel/kernel.o (somthing...) undefined reference to copy_to_user

    what should I do to solve this problem?

    you can include the header file " #include <asm/uacces.h>"

    copy_to_user and copy_from_user

    What these functions(copy_to_user and copy_from_user) are doing?kernal space to user space and user space to kernel space conversion.Really they are doing some memory conversion?
