| |
From: Chris Wilson <chris@chris-wilson.co.uk>
In commit 932066a15335 ("tracing: Default to using trace_global_clock if sched_clock is unstable"), the logic for deciding to override the default clock if unstable was reversed from the earlier posting. I was trying to reduce the width of the message by using an early return rather than a if-block, but reverted back to using the if-block and accidentally left the predicate inverted.
