Subject: [PATCH RT 06/22] rcu: Do not include rtmutex_common.h unconditionally
Date: Mon,  6 Aug 2018 04:17:22 -0500	[thread overview]
Message-ID: <de65a1a830c790099a8e27238566ec8785c7a3b8.1533540554.git.julia@ni.com> (raw)
In-Reply-To: <cover.1533540554.git.julia@ni.com>

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

4.9.115-rt94-rc1 stable review patch.
If you have any objection to the inclusion of this patch, let me know.

--- 8< --- 8< --- 8< ---
[ upstream commit b88697810d7c1d102a529990f9071b0f14cfe6df ]

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.
