Native statvfs() support is my motivation, but I am thinking that if we are going to introduce a new syscall (or version rev the statfs syscall somehow), then we should think hard about what else we can do. More superblock info should be possible, more detailed info like like related mounts will be costlier, so that may be better off as a different syscall. -- 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
