How to register block device as read-only

[beck0778]

Hello,

In a block device driver, how do you tell the kernel that your block device 
is read-only? Is it in the registration of the gendisk, or is there an 
ioctl I should be catching to inform the kernel (and user) that this disk 
is read-only?
