From efefc97736e6f3261879bc9dddcb161224a455f5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 20 Mar 2018 10:11:28 +0100 Subject: jiffies: Introduce USER_TICK_USEC and redefine TICK_USEC Since the subsequent changes will need a TICK_USEC definition analogous to TICK_NSEC, rename the existing TICK_USEC as USER_TICK_USEC, update its users and redefine TICK_USEC accordingly.
