NFSv4 has a concept of a 'root' filehandle (from which all other can
be found via LOOKUP, so no need for mountd).

This patch defines exp_pseudoroot(), which is used to set the filehandle
for the root of the pseudofs. The root is defined to be the export
point with fsid == 0.

Define fh_dup2(), which copies a _verified_ filehandle, taking care
of refcounts accordingly.  (This will be used by RESTOREFH/SAVEFH and
a few other places.)

Instantiate a new file include/linux/nfsd/xdr4.h (server-side XDR for
NFSv4).

All the lockd *_msg requests are implemented by
calling the equivalent non- *_msg request and sending off
the response as a new message (*_res).

For the non- *_msg requests, the response buffer is
pre-zeroed by the RPC layer, but the *_msg handlers weren't
pre-zeroing the buffer, would could in some circumstances lead to
an Oops.

Now we pre-zero them all.

Symlinks in NFSv3 can be upto 1024 bytes, not 256 like nfsv2.

It only gets spam these days...

Don't release NULL resources.

Patch from William Lee Irwin II.

A trivial loose end: add a 'lease_time' field to 'struct nfs_fsinfo'.

Now that all calls to nfs_async_handle_jukebox() have been moved to
fs/nfs/nfs3proc.c, we clean up by moving the nfs_async_jukebox() routine
itself there.  We also rename it nfs3_async_handle_jukebox(), to be
consistent with the naming conventions of that file.

In NFSv3, an RPC is retried if the special error NFSERR_JUKEBOX is
received.  This generic bit of postprocessing happens invisibly for
synchronous RPC's, but in the async case, the ->tk_exit callback
must call nfs_async_handle_jukebox() by hand.

In NFSv4, we also need generic postprocessing of async RPC's, but
the details are different.  Therefore, we don't want to call
nfs_async_handle_jukebox(); we want to call a different, NFSv4-specific
routine.  Therefore, we want to move calls to nfs_async_handle_jukebox()
out of the "generic" NFS code and into NFSv3-specific routines.  This
has already been done for async READ and WRITE in the preceding patches,
but there is still one outstanding case: the async REMOVE in sillyrename.

This patch removes nfs_async_handle_jukebox() from the async sillyrename
path, and puts in the NFSv3 ->unlink_done() rpc_op.

This is a nontrivial change to the NFS client.

This patch does for the async WRITE and COMMIT paths what patch 15
did for the async READ path, by defining new nfs_rpc_ops ->setup_write()
and ->setup_commit().

This is a nontrivial change to the NFS client.

This patch does for the async WRITE and COMMIT paths what patch 14
did for the async READ path, by changing 'struct nfs_write_data'
so that the v2- and v3-specific parts are moved into a private area,
with room for a v4-specific part in parallel.  None of the logic is
changed.

The Nagle algorithm gets in the way when sending short RPC messages to
the server. The following patch from Chuck does the equivalent of
setting TCP_NODELAY on the socket.

The following seems to have survived the purge ..

Fix uniprocessor compilation.

do_timer.h needs asm/mpspec.h for the declaration of `using_apic_timer'

Rework lots of cruft in the aic7xxx_old driver so that it can be more
easily read and understood by other people and so it starts on the road
to giving a clearer picture of how to interact with the scsi mid layer.

This does 4 things.  Fixes the oversight James found about cmd_per_lun.
Makes scsi_adjust_queue_depth() implement the usage of tagged that I
described in my email to linux-scsi.  Updates some comments to highlight
things that are going to go away shortly.  Removes the call to
host->select_queue_depths() entirely since drivers that implement this
will try to set SDptr->queue_depth to the desired depth, which in reality
will do nothing but confuse the mid layer since that is now the actual
allocated command counter, so it won't make the mid layer allocate more
commands, it will make the mid layer think more commands have been
allocated.

Start removing items from scsi.h that are driver specific and provide a
patch to NCR53C9x.? that switches to driver private storage instead as
an example of how drivers should do private struct storage

Also fixes a bug when UTP port is unplugged.

Also some minor cleanups as well.

[This patch qualifies for the cavemen ugh-lympics, because the driver does
some really nasty things in interrupt context and this patch does
not correct that.  However, the patch is an incremental improvement
over the current code so it's still worth applying.  I'll fix it
further if IBM does not fix it first.  -jgarzik]
