Subject: cpufreq: amd-pstate: Use trace_call__##name() at guarded tracepoint call site
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2dad375e5f21223c5ed51dabd9ae22e35db1ab79;p=thirdparty%2Fkernel%2Flinux.git

cpufreq: amd-pstate: Use trace_call__##name() at guarded tracepoint call site

Replace trace_foo() with the new trace_call__foo() at sites already
guarded by trace_foo_enabled(), avoiding a redundant
static_branch_unlikely() re-evaluation inside the tracepoint.
trace_call__foo() calls the tracepoint callbacks directly without
utilizing the static branch again.
