From b75d85218fdfd8774f2f8397d1f6092ed06bd311 Mon Sep 17 00:00:00 2001 From: Vitaly Chikunov Date: Sun, 24 Mar 2024 02:17:04 +0300 Subject: tracing: Fix documentation on tp_printk cmdline option kernel-parameters.txt incorrectly states that workings of kernel.tracepoint_printk sysctl depends on "tracepoint_printk kernel cmdline option", this is a bit misleading for new users since the actual cmdline option name is tp_printk.
