1. Using MNT_FORCE flag does not make sense for nsfs. Using MNT_DETACH
though might help.
2. When -check.vv is added to TESTFLAGS, there are a lot of messages
like this one:
> unmount of /tmp/dxr/d847fd103a4ba/netns failed: invalid argument
and some like
> unmount of /tmp/dxr/dd245af642d94/netns failed: no such file or directory
The first one means directory is not a mount point, the second one
means it's gone. Do ignore both of these.
