From: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Date: Mon Feb 12 18:31:40 2018 +0100 Subject: update timer instrumentation on 4.16 and 4.14-rt Git-commit: 562860aa5d13249d2c80e51080a3437ef5d2fe0b Signed-off-by: Tony Jones <tonyj@suse.de> [SUSE: Adapt to SUSE_KERNEL/RT] Fix: update timer instrumentation on 4.16 and 4.14-rt See upstream commit : commit 63e2ed3659752a4850e0ef3a07f809988fcd74a4 Author: Anna-Maria Gleixner <anna-maria@linutronix.de> Date: Thu Dec 21 11:41:38 2017 +0100 tracing/hrtimer: Print the hrtimer mode in the 'hrtimer_start' tracepoint The 'hrtimer_start' tracepoint lacks the mode information. The mode is important because consecutive starts can switch from ABS to REL or from PINNED to non PINNED. Append the mode field. See linux-rt commit : commit 6ee32a49b1ed61c08ac9f1c9fcbf83d3c749b71d Author: Anna-Maria Gleixner <anna-maria@linutronix.de> Date: Sun Oct 22 23:39:46 2017 +0200 tracing: hrtimer: Print hrtimer mode in hrtimer_start tracepoint The hrtimer_start tracepoint lacks the mode information.
