If so, please use a git based recipe building the HEAD of the latest released
stable branch (stable-2.10 currently since 2.11 is in currently in the RC
stage). If you have problem, report them on our mailing list  or our bug
tracker . We have extensive CI jobs for lttng-modules against the vanilla
kernel  and other usual suspects . We normally catch those problems
quite quickly. Keep in mind that in no way should a production image be built
with a non tagged release.
As for the oe-core recipe, please send us a quick email to let us know, patch
level releases are cheap. Keep in mind that we are chasing a moving target
To add to Mathieu statement, not only do we integrate support for newer kernels into
the current stable branch but also in all the supported stable branch when
possible. The supported stable release are normally the 3 latest minor-level releases.
Currently this set is : 2.8, 2.9, 2.10 .
 An example of such job running: https://ci.lttng.org/view/LTTng-modules/job/lttng-modules_master_build-vanilla/648/console
This job validate that lttng-modules master builds against the following vanilla kernel tags. We have
similar jobs for master, stable 2.11, stable 2.10, stable 2.9, stable 2.10 lttng-modules branch.
