I guess we could update lttng-{libust,modules,tools} to the 2.7.0 version.
This is fixed by http://git.buildroot.net/buildroot/commit/?h=next&id=c2be38b9e3bee22129b9da160a8d131ce4e1efac, which will be part of the 2016.02 release. It was too late for this version bump to be part of 2015.11. |

Using lttng-modules 2.6.4, lttng-ust 2.6.4 and lttng-tools 2.6.1 seems to solve the problem.
