Re: filter drivers in Linux

[Mark Brown <markb@xxxxxxxxxxxxxxxxxxxxx>]

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.

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.
