[PATCH v2 18/19] mm: damon: Use trace_call__##name() at guarded tracepoint call sites
Posted by Vineeth Pillai (Google) 3 hours ago
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.
