* nfsd: pNFS block layout driverChristoph Hellwig2015-02-051-0/+157
Add a small shim between core nfsd and filesystems to translate the somewhat cumbersome pNFS data structures and semantics to something more palatable for Linux filesystems. Thanks to Rick McNeal for the old prototype pNFS blocklayout server code, which gave a lot of inspiration to this version even if no code is left from it. Signed-off-by: Christoph Hellwig <hch@lst.de>
