--- Comment #19 from Andreas Dilger <adilger.kernelbugzilla@dilger.ca> ---
Jan, your example is a red herring, because the removal of mbcache at most
affects the performance and space efficiency, not correctness.

I agree that making mbcache more efficient is a good goal, but I don't think
that ot should block the landing of this patch. Rather, it makes sense to land
the patch and we can still fix mbcache performance if anyone actually wants to
use it. It will also serve as the basis for any heuristic to turn mbcache on
and off dynamically instead of (or in addition to) the mount option.

Laurent, I'd be greatful if you pushed the patch upstream for the latest kernel
as I'm traveling this week.
