>Description:
When I ran the ATF test suite, one error was in the fs/tmpfs/t_vnode_leak section, which showed:

tc-so:Lowering kern.maxvnodes to 2000
tc-so:Executing command [ sysctl -w kern.maxvnodes=2000 ]
tc-se:Fail: incorrect exit status: 1, expected: 0

Running the same command standalone shows a failure:


~~ sysctl -w kern.maxvnodes=2000
sysctl: kern.maxvnodes: Device busy


>How-To-Repeat:
The same results appear on other architectures such as arm64, but did not recur on an i386 install.





>Fix:
Unknown.
