Is the target proc directory in use, such as mounted?

remove_proc_entry() is what the usb subsystem uses to remove its
main usb-fs directory (/proc/bus/usb), and it works.

That's also what the proc-fs example at
http://kernelnewbies.org/documents/kdoc/procfs-guide/example.html
uses. See that document if you haven't already.
