From 755a648e78f12574482d4698d877375793867fa1 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 6 Mar 2026 21:24:03 -0500 Subject: [PATCH] time/jiffies: Mark jiffies_64_to_clock_t() notrace The trace_clock_jiffies() function that handles the "uptime" clock for tracing calls jiffies_64_to_clock_t(). This causes the function tracer to constantly recurse when the tracing clock is set to "uptime". Mark it notrace to prevent unnecessary recursion when using the "uptime" clock.
