[PATCH] kNFSd: Create files: /proc/net/rpc/$CACHENAME/channel for communicating cache updates with kernel
Each cache gets it's own 'channel' at
/proc/net/rpc/$CACHENAME/channel
Reads from the file will return all pending requests, one at a time.
select will block when at end of file.
writes will pass full lines in to be processed.
