You can stack a driver on top of another to enhance functionality. For
an example check the Linux RAID and LVM implementations. In general
you don't need filter drivers because you can modify the Linux kernel
to add functionality, where in Windows you generally cannot.

Dear All
Is there any concept of filter driver in case of Linux like in
windows OS. In windows we can write a filter driver to enhance the
behavior of existing driver and this filter driver can be attached
to main driver either above or below. But I don't see similar
concept in Linux.
Please advise.
