From 7b1c2d7547943ddb0d425138b3b42262ff92eea3 Mon Sep 17 00:00:00 2001 From: "Vineeth Pillai (Google)" Date: Mon, 23 Mar 2026 12:00:21 -0400 Subject: kernel: Use trace_call__##name() at guarded tracepoint call sites 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.
