Hi all,

This series adds 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.

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

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.
