I'm totally agree with that.

Just curious: where have you gotten this insight about dm-cache being
stable and used in production?  That should help dm-cache's cause if it
is submitted for review.
Well I wrote to Ming before post here, and found comments about the module in the project OpenFiler which seem to integrate it : https://forums.openfiler.com/viewtopic.php?id=3595

Writeback support is arguably the most useful aspect of a caching DM
target so emphasis must be placed on its review/implementation.  Using
SSD as a persistent writeback cache should afford us much more fault
tolerance in the face of system crashes during writeback to the slower

Yes it's also for the writeback feature I'm interested.

I don't think be enough skilled to help for update the code, but maybe I can do some tests.
