[PATCHSET,v6,0/7] xfsprogs: add the ability to flag a fs for repair

Message

Hi all,

This series adds userspace support for a new incompat feature flag so
that we can force a sysadmin to run xfs_repair on a filesystem before
mounting.  This will be used in conjunction with v5 feature upgrades.
All of these patches are reviewed and (hopefully) already in Eric's
upstream tree.

v2: tweak the "can't upgrade" behavior and repair messages
v3: improve documentation, define error codes for the upgrade process, and
    only force repair if NEEDSREPAIR is set
v4: move all the upgrader code to xfs_repair per Eric suggestion
v5: various fixes suggested by reviewers, and document deprecated V4 options
v6: break this series into smaller pieces since this is all the reviewed stuff;
    and fix some comments

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
