The patch is really the same. I did not commit it because the branch
was frozen for the release of 4.5.1. I'm re-testing it on the branch
now and hopefully will commit it today.

Actually no, the patch must be slightly different because
scan_function() is not split into multiple functions in 4.5... but
along the same lines. I'll prepare it, hopefully today.
