Comment 2 for bug 1824333

Hi Robert,
I haven't found the reason.
For my limited kernel knowledge I have checked and discussed a bit.

in [1] I found
$ grep -Hrn autofs debian.master/contro*
debian.master/control.d/generic.inclusion-list:181:fs/autofs4/autofs4.ko

But then was made aware that with 4.18 ther kernel started to include this series [2]
Which means it was moved to a different path.

Maybe this would be enough to fix it, btu that is up to the kernel team
