This fixes various issue brought up in comments to the previous version.

Major changes are:
bugfixes and renames in the deviceid cache
fix Kconfig using a suggestion from Trond
moved module_get to simplify and avoid bug in find_pnfs_driver_locked

For those interested, the patches can also be found at
git://linux-nfs.org/~iisaman/linux-pnfs.git,
under the branch devinfo-submit-rc5-trond

A rebase of Benny's pnfs-submit branch onto these patches is under
the branch bennys-pnfs-submit-on-devinfo-rc5


This is the start of code implementing pnfs, based on RFC 5661.  Since
sending the whole thing at once would be overwhelming, we are trying
to break it into bite sized chunks.  This chunk implements the
mount/umount infrastructure, as well as sending the LAYOUTGET and
GETDEVTICEINFO calls on io (but not actually using the information for
io).  Note that two major simplifications to the protocol will be made 
throughout the initial submission process:  only the file layout
driver is considered, and only whole file layouts are requested.


These patches apply against Trond's nfs-for-2.6.37 branch.

patches 01-08 implement the mount/umount hooks
patches 09-12 implement LAYOUTGET and GETDEVICEINFO
