Description

NOHZ infrastructure in the Linux kernel does not support notifiers chains, which does not let LTTng play nicely with low power consumption setups for flight recorder (overwrite mode) live traces. ne way to allow integration between NOHZ and LTTng would be to add support for such notifiers into NOHZ kernel infrastructure.
