Hi Ben,

Thanks for your efforts.

versions that have not been backported

Is there a technical reason for these patches not being backported or is
it simply that never was requested/needed before?

I don't know yet. I will ask upstream.

OVERLAY_FS is one of the features Hitachi wants to use.
I hope you look into this further and I would like to know if other members also want it.

Based on this request, is it possible for you to estimate the effort to
do this?

Not yet, but I will try to get an idea of how large a change is needed.

Ben.

@Takuo is there a kernel developer from Hitachi that would be willing to
work under Ben's supervision/review in backporting these patches?
