[PATCHSET,v24.0,0/3] libxfs: online repair of quota counters

Hi all,

This series uses the inode scanner and live update hook functionality
introduced in the last patchset to implement quotacheck on a live
filesystem.  The quotacheck scrubber builds an incore copy of the
dquot resource usage counters and compares it to the live dquots to
report discrepancies.

If the user chooses to repair the quota counters, the repair function
visits each incore dquot to update the counts from the live information.
The live update hooks are key to keeping the incore copy up to date.

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.
