[PATCH 07/12] locking: Introduce CONFIG_LOCK_INFO

Namhyung Kim
2022-02-08T18:42:56Z

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.
