From: Anna-Maria Gleixner Date: Wed, 20 Dec 2017 17:12:57 +0100 Subject: [PATCH 08/29] tracing/hrtimer: Take all clock bases and modes into account Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.15-rt11.tar.xz So far only CLOCK_MONOTONIC and CLOCK_REALTIME were taken into account as well as HRTIMER_MODE_ABS/REL in hrtimer_init tracepoint. The query for detecting timer mode ABS or REL is not valid, since the introduction of HRTIMER_MODE_PINNED. HRTIMER_MODE_PINNED is not evaluated in hrtimer_init() call. But for the sake of completeness print all given modes.
