Excellent!

As for the rest of your issues, I'll have to retest very slowly using 
your new userspace patches, documenting every step in order.  It will 
also require before/after runs of xfstests.

I do not know what your patches do for filesystems that already had 
quota on them, so I ask you to check one thing.  It looked like the 
result of the normal `quota` command was having issues.  On my root 
filesystem that was mounted uquota only, the following is the normal 
behavior (as an ordinary user):

mls:~$ quota
Disk quotas for user mls (uid 3001):
      Filesystem  blocks   quota   limit   grace   files   quota   limit 
   grace
       /dev/sda1  165955  262144  327680            2345    8194   16384

However, before I switched out kernels here, such a command just left a 
blank, as if there was no quota there.  If you would at that to your 
list of spot-check tests, that would be great.  It might work fine for 
you.  [For the same situation, `xfs_quota -c quota /` worked just fine.]

You're leading a blind man in the dark, so I thank you for your patience.
