I have some questions about the *intended* qgroups semantics, and why we allow certain operations:
1) Why can you create a level 0 qgroup for a non-existent subvolume? It looks like it just gets reset when you create the subvol anyway? Should we prevent this? 2) Why do we allow deleting a level 0 qgroup for a currently existing subvolume? It seems to me that just setting the limit to 0, and/or removing relations would work equally well? Perhaps a new ioctl to clear the qgroup would make sense to do this. 3) Why don't we remove the associated level 0 qgroup when you remove the subvol with that id? 4) I noticed in qgroup.c, one of the outstanding items is to determine how to autocleanup. Are there any stated semantics around that, or opinions? PS: If the answer to any of these is "it just needs to be worked on" -- I'm currently poking around this code path for some enhancements we're doing for our usecase. I'm just trying to figure out how much of what I'm doing is generalizable. -Thanks, Sargun -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
