resolving a *huge* long term fork in the DVB code base). We now have
one DVB codebase so the changes while big are very good news

mapper upcall mechanism.

unix-style uid/gids.

Note that this makes use of the RPC client upcall mechanism
(rpc_pipefs) to notify a userland daemon that does the actual mapping.
The results are then cached in the kernel.
The userland daemon can be downloaded from the CITI NFSv4 page at

already open.

The resulting state is saved in the NFS-specific part of the
struct inode.

Initially we just start with 3 possible states:
  - open for read
  - open for write
  - open for read/write
