util-linux-2.14.1-hwclock_adjust_and_hctosys.patch Normal file
View File

@ -0,0 +1,170 @@
From: Kurt Garloff <garloff@suse.de>
Subject: Allow to combine --adjust and --hctosys
Reference: bnc441106
Waiting for a clock tick twice when calling --adjust and --hctosys
is wasteful. Having to do it once is bad enough.
This patch allows combining the two options.
