This is basically what Viro says in the attached reference. 
My second concern is why the same command (df) should lead to two different 
results only by upgrading the kernel? My feeling is that the df output should 
only give one single outcome for root (/)

Well I just wanted to outline this pecuriality to the developers. As far as 
the patch is concerned I leave that with them to decide whether it should be 
taken into account or not. On the top of that I do not consider myself as a C 
expert :-(
