- This commit introduces the fsmup device, which is a major change in how network file systems are handled. Previously every network file system's fsvol device was directly registered with the MUP. Now there is a single fsmup device that is registered with the MUP; network file systems' fsvol devices register with fsmup instead. The fsmup device maintains a prefix table which it uses to demultiplex and forward requests to the appropriate fsvol device. - This device change was necessatitated to fix issue #87.
