The implicitly declared function warning for __get_cpu_var() is gone, but the implicitly declared function warning for is_running() is still there, which I find odd.

is_running() doesn’t exist anymore in the current version. The reason is that the underlying Linux API cannot be used (any longer) as it was used in prior LITMUS^RT versions.

The replacement is is_current_running(). (There’s also a thread about this in the archives somewhere.)

I’m sorry that you keep running into issues because of the outdated tutorial, but unfortunately LITMUS^RT is completely volunteer-driven and I personally no longer have as much coding-and-documenting time as I used to. Again, any volunteers to step up would be very welcome…
