[Nix-dev] Enabling FTRACE in the 3.2/3.3 kernels

[Lluís Batlle i Rossell]

Hello,

would anyone oppose enabling FTRACE, FUNCTION_TRACER, SCHED_TRACER, and
FTRACE_SYSCALLS in the nixos 3.2 and 3.3 kernels?

I think this allows some better diagnosis of system activities, without much
overhead:
"This way a CONFIG_FUNCTION_TRACER kernel is slightly larger, but
otherwise has native performance as long as no tracing is active."

Regards,
Lluís.
