I don't think this scheme works well. As mentioned earlier XFS doesn't even use vfs dirty tracking at the moment, so introducing this in a hidden way sounds like a bad idea. Probably the same for btrfs.
I'd rather keep update_time as-is for now, don't add ->write_time and let btrfs and XFS figure out how to implement the semantics on their own. -- 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
