This patch tracks dnode usage for each user/group in the DMU_USER/GROUPUSED_OBJECT ZAPs. ZAP entries dedicated to dnode accounting have the key prefixed with "obj-" followed by the UID/GID in string format (as done for the block accounting). A new SPA feature has been added for dnode accounting as well as a new ZPL version. The SPA feature must be enabled in the pool before upgrading the zfs filesystem. During the zfs version upgrade, a "quotacheck" will be executed by marking all dnode as dirty.
