Subject: mm: damon: Use trace_call__##name() at guarded tracepoint call sites
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ec4e50aa07fe9081c28eec8b29c75441f3f868b;p=thirdparty%2Fkernel%2Fstable.git

mm: damon: Use trace_call__##name() at guarded tracepoint call sites

Replace trace_damos_stat_after_apply_interval() with
trace_call__damos_stat_after_apply_interval() at a site already guarded
by an early return when !trace_damos_stat_after_apply_interval_enabled(),
avoiding a redundant static_branch_unlikely() re-evaluation inside the
tracepoint.
