Seems simpler than mucking with "which features > are unique to ext4" I'd do "are we RW mounted with the extents feature". That way we don't need to worry about someone accidentally mounting a partition meant for Hurd using ext4, which would imply delalloc, and then causing Hurd to no longer be able to deal with the file system. That *shouldn't* happen, but if someone accidentally mounts the file system with -t ext4, but it seems safer to gate it on the existence of the extents feature. - 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
