From: Vineeth Pillai <[email protected]> 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/[email protected]/ 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.
