From 73b08d2aa4245806ef1bdd48463e9a0b045c62cf Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 16 Feb 2007 01:27:36 -0800 Subject: [PATCH] clocksource: replace is_continuous by a flag field Using a flag filed allows to encode more than one information into a variable. Preparatory patch for the generic clocksource verification.
