[V5 0/2] Super simple flex file server

[Tom Haynes <thomas.haynes@primarydata.com>]

Hi Bruce,

The following patches make a flex file server in which
the mds and the ds are the same machine. And the same inode
services both metadata and data.

v5:
- Fix the stripe unit size as reported by Tigran

v4:
- The addr len in a netaddr is INET6_ADDRSTRLEN + 8

v3:
- Extra word help for selecting NFSD_FLEXFILELAYOUT
- Do not allow WRITE permissions on an IOMODE_READ segment

v2:
- Remove patch 2: nfsd: Can leak pnfs_block_extent on error
- Consolidate 3rd and 4th patch
- Fix the rsize and wsize to come out of the rqstp as per Jeff's
  review comments
- Sort the available layout types such that scsi beats block which
  beats flex file
- Address the points brought up by Christoph in his review

These patches are also in my flex_server branch at
git://git.linux-nfs.org/projects/loghyr/linux-nfs.git

Thanks,
Tom
