    Subjectaccess_ok problem through system_call

    i'm new to linux kernel programming and i'm having the following problem:

    When trying to use the sys_read and sys_write calls from within another
    system call the return value is -14 (bad address EFAULT). This seems to be
    happening because the 'access_ok' function is not allowing the access to
    the buffer being used to read or write.

    Could someone explain why this is happening? Is it wrong to use
    sys_read/sys_write through another system call?
