Subject: tracing: Remove TRACE_EVENT_FL_USE_CALL_FILTER logic
X-Git-Tag: v4.7-rc1~125^2~1
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=dcb0b5575d24a32f51a3f1003312fb94ed4e214a;p=users%2Fjedix%2Flinux-maple.git
tracing: Remove TRACE_EVENT_FL_USE_CALL_FILTER logic
Nothing sets TRACE_EVENT_FL_USE_CALL_FILTER anymore. Remove it.
