Subject: [PATCH 07/12] locking: Introduce CONFIG_LOCK_INFO
This is a preparatory work to have tracepoints separated from the
lockdep. I'd like to keep minimal information of locks (name, for
now) to be used by the tracepoints in the lockdep_map structure.
To make the work easier, CONFIG_LOCK_INFO was added to indicate that
it needs to save the lock info. And convert existing code using lock
information to depend on it rather than CONFIG_LOCKDEP and/or
CONFIG_DEBUG_LOCK_ALLOC directly. Future users of the lock
information should select it too.
Signed-off-by: Namhyung Kim <namhyung@...nel.org>
