Currently only USER/GROUP quota are supported bu linux quota But sometimes it is reasonable to have other types of quota For example: 1) project_id in XFS 2) container_id in container(chroot) solutions. This patch series is aimed to extend quota interface to support different quota types. Last patch add the SUBTREE quota type. This patch series does not contain fs-related part of subtree-quota-type support. This is because generic subtree support is relatively independent from quota part. And in fact patches depends on two different devel trees linux-fs.2.6 and ext4.git. So i've divided big subtree patchset in to generic fs-related and quota-related parts. First tree patches performs necessary cleanup work, And the last one extends quota to support new quota's type. Changes from v1: - fixes suggested by Jan Kara - redesign get_id() callback. Initially i've overlooked a quota transfer case. We have to pass new id's array to get_id() and it will return corresponding quota id. - fix hard-coded values in dquot_initialize() Signed-off-by: Dmitry Monakhov <dmonakhov@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
