Why don't we implement the lseek function in the fops of block
devices? If a seek to the end of a block device special file were
possible, programs could find out the length of a partition without
having to use ioctl(BLKGETSIZE) - they could simply fseek to the end
and use ftell(), which is the standard technique for ordinary files.
There would be a simple way to implement this, by providing a generic
function block_lseek (just like block_read), which would eventually
use the BLKGETSIZE ioctl transparently.
