System: NetBSD night-owl.duskware.de 8.99.6 NetBSD 8.99.6 (NIGHT-OWL) #555: Tue Nov 14 10:04:20 CET 2017 martin@night-owl.duskware.de:/usr/src/sys/arch/amd64/compile/NIGHT-OWL amd64

>Description:

While trying to fix PR kern/51762 I noticed that rumpfs never updates the
mtime of anything. The only time a time stamp is set is during setattr VOP
calls setting one of the time stamps externaly, and during initial vnode
creation in makeprivate().

>How-To-Repeat:

Write something on rumpfs, check stat(2) values of mtime before and after.
ATF test program will be added ASAP.

>Fix:
n/a
