pnfsblock: cleanup nfs4_blkdev_get (2012-10-08 19:32:40 -0400)

----------------------------------------------------------------
NFS client updates for Linux 3.7

Features include:

- Remove CONFIG_EXPERIMENTAL dependency from NFSv4.1
Aside from the issues discussed at the LKS, distros are shipping
NFSv4.1 with all the trimmings.
- Fix fdatasync()/fsync() for the corner case of a server reboot.
- NFSv4 OPEN access fix: finally distinguish correctly between
open-for-read and open-for-execute permissions in all situations.
- Ensure that the TCP socket is closed when we're in CLOSE_WAIT
- More idmapper bugfixes
- Lots of pNFS bugfixes and cleanups to remove unnecessary state and
make the code easier to read.
- In cases where a pNFS read or write fails, allow the client to
resume trying layoutgets after two minutes of read/write-through-mds.
- More net namespace fixes to the NFSv4 callback code.
- More net namespace fixes to the NFSv3 locking code.
- More NFSv4 migration preparatory patches.
Including patches to detect network trunking in both NFSv4 and NFSv4.1
- pNFS block updates to optimise LAYOUTGET calls.
