The XFS-compatible project quota is effectively a subtree quota system. My argument is that if we're going to try to get something like this upstream, it should have the same properties as the XFS project quota system; and that should be semantically compatible with the patches you are using. (If we end up using the same ioctl's as xfs_quota uses, which in theory I'm in favor of, but which I haven't studied yet, then it might not be ABI compatible with Dmitry's patches, but it should simplify the patches that OpenVZ would need to carry.) - 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
