[PATCH] score: Rename watchdog variants

Sebastian Huber sebastian.huber at embedded-brains.de
Mon Oct 16 06:02:29 UTC 2017


Rename PER_CPU_WATCHDOG_RELATIVE in PER_CPU_WATCHDOG_MONOTONIC to
highlight the corresponding POSIX CLOCK_MONOTONIC.

Rename PER_CPU_WATCHDOG_ABSOLUTE in PER_CPU_WATCHDOG_REALTIME to
highlight the corresponding POSIX CLOCK_REALTIME.

Update #3117.
Update #3182.
