This set improves the blocklayoutdriver's handling of layouts when devices are not present on the a client, or become unavailable. Ideally, clients should not continually spam a server with LAYOUTGET for known layouts, and GETDEVINFO for known devices, since it may be a common scenario to have some clients that have access to the block devices, and some clients that do not. In addition to better handling situations where devices are unavailable, patches 2 and 3 fix crashes if SCSI devices do not exist or are already have existing reservations.
