The ida index management routines are used in several driver modules to manage allocation and release of index values. Reviewing the way in which the ida routines were called, together with the small number of such clients, led to the belief that these users should all be able to share a simple built-in lock in the ida module by calling the ida_simple_*() functions instead of the non-simple versions. This means that ida does all the required locking so that clients don't have to manage that. This will greatly simplify the client calling code, and if there is any problem with these clients sharing a "simple" lock, the ida code can be transparently expanded to allocate a lock per client, without having to change any of the clients again. NOTE: this patch series replaces an earlier attempt to create a new set of ida helper functions titled: "Create and use ida and idr helper routines" Another set will soon be sent out soon to (1) add idr helper functions, (2) modify clients to use them, and (3) update SCSI host_no to use them.
