I've created an updated quota design document here: https://ext4.wiki.kernel.org/index.php/Design_For_1st_Class_Quota_in_Ext4 No major changes from last time. One new thing is a proposed (optional) change to the quota format, to use the 32-bit dqpb_pad field in the v2r1 on-disk quota structure as a 32-bit CRC of the quota entry. This would allow the quota system to detect corrupted quota entries.
