Re: [PATCH v5 26/29] sched/debug: Show the deadline bandwidth of each runqueue

I did not know that script, thanks. It shows more than this patch does.

The two lines are there for the selftests. params_waking and random_mix
of deadline_bw_test read running_bw and this_bw of each CPU from
/sys/kernel/debug/sched/debug. A selftest cannot rely on drgn and on
the debug information of the running kernel.

So I would keep the patch as it is. I would not add extra_bw: no test
reads it, and your script has it.

Thanks,

Mathieu
