ext3-quota-setattr-fix.patch

   1 ext3: fix incorrect block reservation on quota transfer.
   2
   3 Inside ->setattr() call  both ATTR_UID and ATTR_GID may be valid
   4 This means that we may end-up with transering all quotas. Add we have
   5 to reserve QUOTA_DEL_BLOCKS for all quotas, as we do in case of
   6 QUOTA_INIT_BLOCKS.
