Thanks for the pointer! Sorry I didn't see that patch series already: My search skills need some work... In any case, there's no good reason for me to duplicate work.
I should probably comment on that series directly, but I'll note that one thing I tried to do with the sysfs attributes here was avoid racing with user space. The uevent is suppressed until all the related files are created in sysfs. See http://kroah.com/log/blog/2013/06/26/how-to-create-a-sysfs-file-correctly/ for Greg's explanation of a scenario.
