[PATCH 0/1] Update scsi hosts to use idr for host number mgmt

[Lee Duncan <lduncan@suse.com>]

This is an updated version of a patch I submitted a few days ago.

The previous versions of this patch updated the scsi hosts module
to use the ida helper routines to allocate host numbers, instead
of using a simple integer.

Based on a suggestion by Christoph Hellwig, I decided to use the
idr helper routines instead of the ida set, since the idr functions
can also associate a pointer with an index.

This patch uses idr to manage the host number index as well
as to simplify looking up a host based on that index.

No helper routines were supplied/needed since the users
of these APIs do not seem to have uniform calling sequences.

A separate patch sequence follows which will add helper routines
for the ida index functions.
