[lttng-dev] Clarification on SCHED_FIFO support

Greetings!

We are exploring the LTTng Kernel Tracer (version 2.9) on Ubuntu 16.04. We
are particularly interested in real-time applications. As far as we
explored, we couldn't find support for SCHED_FIFO events. Also, we found a
comment in the source code (.../sched.h) indicating that the
sched_stat support to SCHED_FIFO/RR is yet to be added.

*So we would like to confirm if SCHED_FIFO isn't supported in the latest
version of the tool.*

Thanks,
Sukanya
