From 916c7a855174e3b53d182b97a26b2e27a29726a1 Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Wed, 20 Aug 2008 16:46:08 -0700 Subject: ntp: fix ADJ_OFFSET_SS_READ bug and do_adjtimex() cleanup Thanks to the review by Michael Kerrisk a bug in the recent ADJ_OFFSET_SS_READ option was discovered, where the ntp time_offset was inadvertently set by it. This fixes this by making the adjtime code more separate from the ntp_adjtime code (both of which really want to be separate syscalls).
