When we change the namespace tag of a sysfs entry, the associated dentry
is still kept around. readdir() will work correctly and not display the
old entries, but open() will still succeed, so will reads and writes.

Note reads and writes of file handles open before the move should
continue to work.

Well, yes. But do you see it as a big problem?

This can probably be fixed as well, but I foresee a big hackishness in
the way =p
