Those were added as part of the kill-the-BKL project. They used to be
done as #defines to lock_kernel and unlock_kernel, but became full-fledged
functions in this release. Unfortunately, if you build with CONFIG_FILE_LOCKING=n
you need to provide a dummy stub, which is what was intended here.

Does the following (untested) fix the problem for you?
