Most of this can be trivially moved to a private header as well.

* Add includes that are directly used by headers
* Remove includes that are not needed
These are the changes made:
[xdr.h]
struct nfsd_readdirres has an embedded struct readdir_cd from nfsd.h
fixing that we can drop other includes
[xdr4.h]
embedded types defined both at state.h and nfsd.h
[syscall.h]
After export.h fix none of these stuff is needed.
fix extra space in # include <> statement
[stats.h]
does not need <linux/nfs4.h> but was export to user-mode
so I don't touch it
[state.h]
embedded types from nfsfh.h like struct knfsd_fh. bringing that
eliminates the need for all other includes
[nfsfh.h]
directly manipulating types from sunrpc/svc.h.
Removed Other unused headers.
[nfsd.h]
removed unused headers include
[export.h]
lots of sunrpc/svc.h types and a single prototype declaration
with pointer from nfsfh.h, but all users of export.h do need
nfsfh.h any way. remove now un-needed include.
[const.h]
Unfixed (not independent)
[cache.h]
could do with a forward declaration of "struct svc_rqst;"
from sunrpc/svc.h but all users absolutely will need
sunrpc/svc.h it is easier overall this way.

ext4 supports a real NFSv4 change attribute, which is bumped whenever
the ctime would be updated, including times when two updates arrive
within a jiffy of each other. (Note that although ext4 has space for
nanosecond-precision ctime, the real resolution is lower: it actually
uses jiffies as the time-source.) This ensures clients will invalidate
their caches when they need to.
There is some fear that keeping the i_version up-to-date could have
performance drawbacks, so for now it's turned on only by a mount option.
We hope to do something better eventually.

Modify the NFS server code to support 64 bit ino's, as
appropriate for the system and the NFS protocol version.
The gist of the changes is to query the underlying file system
for attributes and not just to use the cached attributes in the
inode. For this specific purpose, the inode only contains an
ino field which unsigned long, which is large enough on 64 bit
platforms, but is not large enough on 32 bit platforms.
I haven't been able to find any reason why ->getattr can't be called
while i_mutex. The specification indicates that i_mutex is not
required to be held in order to invoke ->getattr, but it doesn't say
that i_mutex can't be held while invoking ->getattr.
I also haven't come to any conclusions regarding the value of
lease_get_mtime() and whether it should or should not be invoked
by fill_post_wcc() too. I chose not to change this because I
thought that it was safer to leave well enough alone. If we
decide to make a change, it can be done separately.

Add support for using a filesystem UUID to identify and export point in the
filehandle.
For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room. For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.
When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.

A couple of the warnings will be followed by an Oops if they ever fire, so may
as well be BUG_ON. Another isn't obviously fatal but has never been known to
fire, so make it a WARN_ON.

This eliminates the i_blksize field from struct inode. Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.
Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
