Subject: [PATCH 348/365] rcu: Do not include rtmutex_common.h unconditionally
|
|
|
|
[ 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.
