+Subject: [PATCH] BUILD_RUNTIME_BUG_ON vs gcc7
+
+Avoid using LTTng's BUILD_RUNTIME_BUG_ON macro, as it appears to run
+into a similar problem as Linux experienced with ilog2.
+
+See:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=474c90156c8dcc2fa815e6716cc9394d7930cb9c
