| |
Hi
Imagine we have a virtual disk which provides a 64bit (sparse) address room. Unfortunately we can not use it as a block device because in a lot of places (including buffer_head structure), we're using a long or even an int for the block number.
Is there any way of getting a standardized way of doing I/O to a block device which could handle 64bit addresses for the block number?
Don't you think that we will run into problems anyway because soon there will be raid systems with a couple of Terrabytes of space to waste for mp3's ;-)
