From 8b94247342c5d606af162aa4da6618481d9c1ca0 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 31 Aug 2016 09:52:16 -0700 Subject: [PATCH] ANDROID: rcu_sync: Export rcu_sync_lockdep_assert x86_64:allmodconfig fails to build with the following error. ERROR: "rcu_sync_lockdep_assert" [kernel/locking/locktorture.ko] undefined! Introduced by commit 3228c5eb7af2 ("RFC: FROMLIST: locking/percpu-rwsem: Optimize readers and reduce global impact"). The applied upstream version exports the missing symbol, so let's do the same. Change-Id: If4e516715c3415fe8c82090f287174857561550d Fixes: 3228c5eb7af2 ("RFC: FROMLIST: locking/percpu-rwsem: Optimize ...")
