Hi Tom,
Older userspace or existing DUP's doesn't work with your patch & CONFIG_FW_LOADER_USER_HELPER=n.
I will give a try with https://lkml.org/lkml/2014/6/4/327 new patch & let you know ASAP.
Regards Balaji Singh

Thanks for testing! May I ask if the dell_rbu still works with my patch and CONFIG_FW_LOADER_USER_HELPER=n with the old userspace? The intention was that you should not need to change anything in userspace at all.
By the way, there is now a new version of this patch: , which should allow your (old or new userspace) Dell RBU to work with FW_LOADER_USER_HELPER_FALLBACK=n, so maybe it would be best to test that instead.
Cheers,
Tom
