-Subject: [PATCH 06/11] lockdep/selftests: Avoid using
- local_lock_{acquire|release}().
-
-The local_lock related functions
-  local_lock_acquire()
-  local_lock_release()
-
-are part of the internal implementation and should be avoided.
-Define the lock as DEFINE_PER_CPU so the normal local_lock() function
-can be used.
