Subject: [PATCH v3 09/11] net: devlink: Use trace_call__##name() at guarded tracepoint call sites
Date: Fri, 15 May 2026 09:59:53 -0400 [thread overview]
Message-ID: <20260515135953.2238907-1-vineeth@bitbyteword.org> (raw)
From: Vineeth Pillai <vineeth@bitbyteword.org>
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.
Original v2 series:
https://lore.kernel.org/linux-trace-kernel/20260323160052.17528-1-vineeth@bitbyteword.org/
Parts of the original v2 series have already been merged in mainline.
This patch is being reposted as a follow-up cleanup for the remaining
unmerged pieces.
