pnfs git tree status pnfs-all-2.6.38-rc3-2011-02-03

[Benny Halevy <bhalevy@panasas.com>]

I rebased the pnfs tree onto 2.6.38-rc3, with Fred's lock inversion fix in place
and Andy's reordering of pnfs-submit for wave3 and wave4.
pnfs-all-latest tip is tagged as pnfs-all-2.6.38-rc3-2011-02-03

Note: spnfs-block is currently broken due to the fallocate() API change.

Cumulative patches can be generated from
git://linux-nfs.org/~bhalevy/linux-pnfs.git

A new branch, pnfs-submit-wave3 points at wave3 candidate patches
and pnfs-submit points at current wave4 patches.
