I don't see why.  Support for 4.10 has been in lttng-modules' stable-2.9
branch since January, and is included in the v2.9.1 release, which was
tagged a week ago, right before the 4.10 release.  I had intended to
send the update for lttng-modules on Monday but since I've got it ready
I'll send it in a few minutes.

You should not need to use lttng-modules' master branch to work with
released Linux versions.

That's not my impression at all. The LTTng project diligently tracks
upstream kernel development and ensures that the latest stable branch of
lttng-modules supports the latest released kernel.

Maintaining a set of patches on top of the released version of
lttng-modules should not be necessary.

I know there's a diversity of opinion on the subject in general, but in
the absence of a need to use git, I think using a release tarball should
be preferred.
