What if we call it a "quota group", with the rules that if a parent directory has a quota group, any files or directories created in that parent directory will inherit that quota group, and only processes with CAP_SYS_ADMIN can change it. And then what if we simply make the rule that if an inode has a quota group, the quota is charged against two group id's; the group id named in inode, and the quota group? That is, do we really need to have a separate namespace for group ids and "subtrees" or "namespaces"? That means we don't have to change the userspace quota tools and we can leverage the existing ways people are used to managing group quotas. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
