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:
<https://lkml.org/lkml/2014/6/4/327>, 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
