media removed indication!

[Jinu M.]

Hi all,

We are working on the removable media support for our disk driver. 

I have a couple of questions.

How do you ask the file system to stop sending buffers to our disk driver (request function) when the media is removed?

If a disk is already mounted when the media is removed is there a way to stop all IO and umount the disk automatically?

Any pointers on the same will be of great help.

Thanks,
-Jinu
