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. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
