Trond,
This patchset includes the latest fixes from Boaz and it is ready
in my opinion for linux-next.
Last 5 patches include the changes we discussed for pg_test and
their use by pnfs-obj, please review carefully.
Note that I skipped v7. It was pushed up to the git tree but no patches were sent.
I released the series to git://linux-nfs.org/~bhalevy/linux-pnfs.git pnfs-submit
under this tag: pnfs-for-2.6.40-v8-2011-05-25
Rebased on top of it are the pnfs-obj, pnfs, pnfsd-all, pnfsd-lexp-all,
and pnfs-exofs-all branches, marked with tag pnfs-exofs-all-2.6.39-2011-05-25
