There is no 8.4 in "vanilla" yet.
3.7 should be more like 8.3.13
The next merge window (so, 3.8) should see the equivalent of 8.4.2,
plus patches (whatever comes up during the merge window).

That's the fate of out of tree modules:
they may break when the in-tree code changes.
Until those changes have been dealt with.
Which, btw, we did about two or three weeks ago, by pure chance.
Usually we do not do compat patches for the out-of-tree DRBD until the
upstream release tag is cut.

Are you comparing external 8.4.2 and in-kernel 8.3.13 ?

Maybe you should get your DRBD (and Support) from LINBIT instead.
