Well ... I thought the element "bd_inode" will be removed from the 
device structure. But it is heavily used! "mapping" is used in lots of 
page manipulation functions, and the only way I found to reach the 
address space (mapping) of a device is using bd_inode! For example 
btrfs, in development, uses it.
So I must be wrong and "will die" shall mean anything else.

I still have a lot to learn anyway ...


Thanks
