I forgot to menton why I was curious. Basically it is "protect me from myself". I've seen a number of people here post about Linux in an LPAR, not as z/VM guest, and sharing DASD. They, like me, are likely from a z/OS background where we've done this for decades reliably (and sometimes not so reliably). If the "mount" command could put a reserve up on the DASD volume containing the filesystem, that would simply make it impossible for another Linux instance to do a mount for a filesystem on that same DASD volume. It literally could not get access to the DASD device.
OK, it is stupid.
