At the moment I don't have any plan to do that, because the cure (potentially breaking userland scripts that are writing to some read/write attributes, by breaking ABI to move everything into a new directory) seems worse than the disease (having some attributes in a directory that isn't the ideal one). I'd be willing to explore something like Venkat's idea if the block layer maintainers insist, though. - Chris. -- Chris Ball <cjb@xxxxxxxxxx> <http://printf.net/> One Laptop Per Child -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
