From c869ca3c032983d590c1ab311edcb6006483430d Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 28 Feb 2012 19:06:50 +0100 Subject: [PATCH 016/298] time: Remove bogus comments There is no global irq lock which makes a syscall magically SMP safe. Remove the outdated comment concerning do_settimeofday() as well.
