When device is hot-unplugged, the device fd will be deleted in kernel.

If this happens, then it is a kernel bug and the kernel should be fixed.
Working around it in userspace is not a great long term solution.
agree with you. The key is sometime hold by kernel. But i think it is at
least reasonable for avoiding no-use process in user space, whatever
kernel's behavior. I am not sure if there is any better idea we can
find, but seems it is an option now.
