[PATCH] cciss: new disk register/deregister routines
This patch removes a couple of functions dealing with configuration and
replaces them with new functions. This implementation fixes some bugs
associated with the ACUXE. It also allows a logical volume to be removed from
the middle without deleting all volumes behind it.
If a user has 5 logical volumes and decides he wants to reconfigure volume
number 3, he can now do that without removing volumes 4 & 5 first. This code
has been tested in our labs against all application software.
