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-rt13.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.
