From 2c6b47de17c75d553de3e2fb426d8298d2074585 Mon Sep 17 00:00:00 2001 From: john stultz Date: Tue, 24 Jul 2007 17:47:43 -0700 Subject: Cleanup non-arch xtime uses, use get_seconds() or current_kernel_time(). This avoids use of the kernel-internal "xtime" variable directly outside of the actual time-related functions. Instead, use the helper functions that we already have available to us. This doesn't actually change any behaviour, but this will allow us to fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ (because much of the realtime information is maintained as separate offsets to 'xtime'), which has caused interfaces that use xtime directly to get a time that is out of sync with the real-time clock by up to a third of a second or so.
