b12a05cbdf nfsd4: cl_count is unused
Now that the shutdown sequence guarantees callbacks are shut down before
the client is destroyed, we no longer have a use for cl_count.

We'll probably reinstate a reference count on the client some day, but
it will be held by users other than callbacks.

b5a1a81e5c nfsd4: don't sleep in lease-break callback
The NFSv4 server's fl_break callback can sleep (dropping the BKL), in
order to allocate a new rpc task to send a recall to the client.

As far as I can tell this doesn't cause any races in the current code,
but the analysis is difficult.  Also, the sleep here may complicate the
move away from the BKL.

So, just schedule some work to do the job for us instead.  The work will
later also prove useful for restarting a call after the callback
information is changed.

227f98d98d nfsd4: preallocate nfs4_rpc_args
Instead of allocating this small structure, just include it in the
delegation.

The nfsd4_callback structure isn't really necessary yet, but we plan to
add to it all the information necessary to perform a callback.

7663dacd92 nfsd: remove pointless paths in file headers
The new .h files have paths at the top that are now out of date.  While
we're here, just remove all of those from fs/nfsd; they never served any
purpose.

1557aca790 nfsd: move most of nfsfh.h to fs/nfsd
Most of this can be trivially moved to a private header as well.

9a74af2133 nfsd: Move private headers to source directory
Lots of include/linux/nfsd/* headers are only used by
nfsd module. Move them to the source directory
