From b88697810d7c1d102a529990f9071b0f14cfe6df Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 18 Oct 2017 08:33:44 -0700 Subject: rcu: Do not include rtmutex_common.h unconditionally This commit adjusts include files and provides definitions in preparation for suppressing lockdep false-positive ->boost_mtx complaints. Without this preparation, architectures not supporting rt_mutex will get build failures. Reported-by: kbuild test robot Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Paul E.
