some questions on the minor number of device
hi, dear all

Now I have a problem on the minor number of device.

I have many sd disks. The sd driver will create many minor numbers for these disks when attached.
But the sd driver may be not remove thest minor number when detached.

The minor number will become very big If I attach and detach these disks again and again.
And at last thest disks will be attached failed because the reason "WARNING: sd32845:a minor 0x40268 too big for 32-bit applications"

So my question is:
1)Why the sd driver create the minor number but not to remove it?
Need I remove these minor numbers by myself?
If I need , how?
2)How can I do if the disks attached failed because the minor number is too big?

Thanks!
