The consequence of the bug is that fini calls are not done when a slab is freed by a call-back from the page daemon. It went unnoticed for two months because fini is little used. I spotted the bug while reading the code to learn how it works so I could write it up for the next edition of the Design and Implementation of FreeBSD book. No MFC needed as this code exists only in HEAD.
