--- Comment #15 from Dimitry Andric <dim@FreeBSD.org> ---
I bisected last evening, building GENERIC from r335000 to r340156:

$ grep 'number of types' *.txt
types-r335000.txt:  total number of types               =3D 29914
types-r338000.txt:  total number of types               =3D 30049
types-r339000.txt:  total number of types               =3D 30086
types-r339300.txt:  total number of types               =3D 30087
types-r339400.txt:  total number of types               =3D 30110
types-r339450.txt:  total number of types               =3D 30110
types-r339460.txt:  total number of types               =3D 30111
types-r339465.txt:  total number of types               =3D 30111
types-r339467.txt:  total number of types               =3D 30111
types-r339468.txt:  total number of types               =3D 35162
types-r339470.txt:  total number of types               =3D 35162
types-r339475.txt:  total number of types               =3D 35162
types-r339500.txt:  total number of types               =3D 35162
types-r340156.txt:  total number of types               =3D 36685

So it seems r339468 ("Replace ttyprintf with sbuf_printf and tty drain rout=
ine
") by itself increases the number of types by almost 5000!  Strangely enoug=
h,
nothing in the commit indicates this, and the author also didn't expect it.

There is likely something else going on too.
