I have used the copy_to_user() in the 2.6 kernel (actually 2.6.5-mm1
gentoo kernel) and it works fine. A simple usage example:

char text_data[]="Blah Blah Blah";
ssize_t text_read (struct file *filp, char *buf, size_t count, loff_t *pos) {
  ssize_t result=0;
  if (copy_to_user (buffer, text_data, sizeof (text_data)-1)) {
    result=-EFAULT;
    return;
  }
  else
    return result;
}

Regards,

Shaks
