Subject: context_tracking: Enable probes by default for selftesting
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8b43876643a737bb74a0e1e557f634eb2453948b;p=linux-beck.git

context_tracking: Enable probes by default for selftesting

Until we provide the nohz_mask boot parameter, keeping
the context tracking probes disabled by default is pointless
since what we want is to runtime test this code anyway.

It's furthermore confusing for the users which don't expect
the probes to be off when they select RCU user mode or full
dynticks cputime accounting.

Let's enable these probes selftests by default for now.
