kernel/locking/lockdep.c deals with validating locking scenarios for various architectures supported by the kernel. There isn't anything kernel specific going on in lockdep, and when we compare userspace to other architectures that don't have to deal with irqs such as s390, they become all too similar. We wrap kernel/locking/lockdep.c and include/linux/lockdep.h with several headers which allow us to build and use lockdep from userspace. We don't touch the kernel code itself which means that any work done on lockdep in the kernel will automatically benefit userspace lockdep as well!
