Since sending the whole thing at once would be overwhelming, we are trying to break it into bite sized chunks. This chunk implements the mount/umount infrastructure, as well as sending the LAYOUTGET and GETDEVTICEINFO calls on io (but not actually using the information for io). Note that two major simplifications to the protocol will be made throughout the initial submission process: only the file layout driver is considered, and only whole file layouts are requested. These patches apply against Trond's nfs-for-2.6.37 branch. patches 01-08 implement the mount/umount hooks patches 09-13 implement LAYOUTGET and GETDEVICEINFO
