[PATCH 2/6] genhd: Rename get_disk() to get_disk_and_module()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Rename get_disk() to get_disk_and_module() to make sure what the
function does. It's not a great name but at least it is now clear that
put_disk() is not it's counterpart.
