That commit e7c87bef7de2417b219d4dbfe8d33a0098a8df54 went into v4.3-rc4
and is required to fix dd2f6c4481debfa389c1f2b2b1d5bd6449c42611, which
was introduced with 3.18-rc1. As thus I recommend back-porting that fix
and inclusion into
 4.2
 4.1
 4.0
 3.19
 3.18
The patch is simple enough to be cherry-picked into each branch without
any fuzz.

We hit that bug and Ubuntu did too:

Thanks.
