I think we agree that the ubifs implementation isn't optimal. But this 
patch only fix a problem for SPL if UBIFS is enabled in u-boot proper. 
The wrong implementation was accept by u-boot 7 years ago.

The problem for me is that we no longer use UBI. I fear that a rework of 
UBI needs a lot of time to to fix a 'should not'. On the other hand I 
have patches with an unclear status that fix problems / incompatibilities.
