Simple block driver example

I just ported the simple block driver to 2.6.31 - see A Simple Block Driver for Linux Kernel 2.6.31

Since the changes to the block driver API in 2.6.31, has there been an update to this example block driver?

I have a small, simple block device that I used the LDDv3 example as a basis for my code. However, I'm having a hard time figuring out what I need to change in order to get it to work with the new API.

Thanks

Now that the driver is written and installed, I can use the open(), release() ... system calls to access it.

How do I get to the request que from my application?

What "h" file do I include and what is the format for the request() call?

Thank you,
Mona
