Description: Displays the usage count (number of opens) of logical drive Y
of controller X.

+Date: February 2011

+Description: Value of 1 indicates the controller can honor the reset_devices
+ kernel parameter. Value of 0 indicates reset_devices cannot be
+ honored. This is to allow, for example, kexec tools to be able
+ to warn the user if they designate an unresettable device as
+ a dump device, as kdump requires resetting the device in order
+ to work reliably.
