Hi Kai,

I've heard rumours that layering bcache with other block device drivers
might not be recommended... I wonder what the truth really is... perhaps
someone can advise.

I think this is not just rumours. Multiple people reported problems when
layering caching or backing devices on top of MD devices. This may be an
implementation problem in MD which is gone in later kernel versions [...]

being rather new to bcache, I did only browse the last few months of  
mailing list history - are you saying that these problems were fixed  
(or simply vanished) some point after 3.18.8? Because if so, I'd of  
course try to upgrade our servers to a more recent kernel :)

Regards,
Jens
