(from oldest to newest). And that's just from 3.16 to 3.17-rc3, going
all the way back to 3.10 would be a lot of work. If there's anyone that
cares about bcache on stable kernels (and actually use it), now would be
a good time to pipe up.

Just "piping up" as I care about bcache and actually use it in production on 3.10! Shame I don't have the knowledge to try and backport these though :-)

I'm "piping up" as well, I use bcache on 3.10 in production.

More "piping up": we currently use bcache on a few nodes in production, on 3.14 and 3.15, and plan to roll it out on a wider scale now.
If necessary we'll go with these kernels, but we'd certainly prefer our usual 3.10-based CentOS kernel.

OK, so we definitely have people using it in production. My concern was
that whomever does the backport of the appropriate patches to 3.10/14/15
stable would have an audience for getting some amount of testing of such
a patch series.

Now we just need someone to line up to do the work...
