There's not a lot of code under #ifdef/#ifndef CONFIG_SYSFS_DEPRECATED, but since I'm not familiar with any of it I don't expect trying to locate the bug on my own would be very productive. Neil, do you have CONFIG_SYSFS_DEPRECATED enabled? If so, does disabling it reproduce my problem? If you can't reproduce it, should it take the problem over to linux-kernel?
