[pnfs] new version of the nfs41/pnfs patchsets in linux-pnfs-bh

[Benny Halevy]

I reworked the nfs41 patches to bring them into a maintainable
(and reviewable) state.  In the process I did more cleanups
and fixed a few bugs (listed below).

You can find the new patches in git://linux-nfs.org/~bhalevy/linux-pnfs.git
in the nfs41 and pnfs branches which are sync'ed with the {nfs41,pnfs}-draft-13-2.6.24-rc5-v1
tags respectively. I also saved intermediate views of the patchsets under the
following tags, if anyone wants to take a closer look at what I did:

[Note: to get the list of "interesting" tags run "git-tag -l nfs"
with git version 1.5.2 or "git-tag -l "*nfs*"" with git 1.5.3]

* {nfs41,pnfs}-draft-13-2.6.24-rc5-v0cu is a cleanup of nfs41-draft-13-2.6.24-rc5-v0
	- Here I broke the whole diff into a comprehensible patchset
	- plus, I fixed	some whitespaces and ifdefs

* nfs41-draft-13-2.6.24-rc5-v0cu-patched
	has the following fixes:

    nfs41: use NFS4_MAX_SESSIONID_LEN rather than SESSIONID_SIZE

    One, SESSIONID_SIZE was erroneously defined as 128
    and also no need for a redundant definition
