Confirm that it fixes firmwared for me.
Also, I am 100% sure that the commit that actually breaks firmwared for me is 4d03e3cc5982 ("fs: don't allow kernel reads and writes without iter ops") which is one commit right before 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") . I just verified it again.
Thank you, Robert
