how to detect whether the mmc card has been removed or the driver rmmoded

I would like to know if my device has been removed from slot or the user has been rmmoded the driver from my driver's 'remove' callback. For your information, this is a mmc driver. Please let me know how to detect it. Any kind of code/link will be very much helpful,

Thanks in advance,

I would simply use the "lsmod" command to know which drivers are still loaded .

Drivers may have a delay_use option though .

However , if the driver does not allow the registration of a device , it would not show in /sys/block or /sys/class/block .

The only solution would be to compile the driver inside the kernel and disable the restart of the computer with unwanted parameters to the driver .
