When NFSv4 is used there are no such logs as NFSv4 does not have a distinct "mount" request. However mountd still knows about which filesysytems are being accessed from which clients, and can actually provide more reliable logs than it currently does, though they must be more verbose - with periodic "is being accessed" message replacing a single "was mounted" message. This series adds support for that logging, and adds some related improvements to make the logs as useful as possible.
