It would be preferable from a usability point of view to have the existing quota tools to work with the new quota files instead of having to introduce new quota utilities. There are a number of ways that this could be facilitated: - make the quota files visible to userspace, but immutable - add the needed calls to the existing quota tools and use them when manipulating quotas on ext4 filesystems with this feature - add library interfaces for doing the quota changes to libext2fs (or a new very simple library) and have the quota tools link to that instead of interfacing to the kernel directly Cheers, Andreas-- 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
