From 72199320d49dbafa1a99f94f1cd60dc90035c154 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 1 Mar 2018 17:33:32 +0100 Subject: timekeeping: Add the new CLOCK_MONOTONIC_ACTIVE clock The planned change to unify the behaviour of the MONOTONIC and BOOTTIME clocks vs. suspend removes the ability to retrieve the active non-suspended time of a system. Provide a new CLOCK_MONOTONIC_ACTIVE clock which returns the active non-suspended time of the system via clock_gettime(). This preserves the old behaviour of CLOCK_MONOTONIC before the BOOTTIME/MONOTONIC unification. This new clock also allows applications to detect programmatically that the MONOTONIC and BOOTTIME clocks are identical.
