In all other cases, the securityfs files are directly created in
ima_fs_ns_init().   What is different about "active" that a new
function is defined?

It was meant as a function to create namespace-specific files, if more 
were to come along.  I can move the code from ima_fs_add_ns_files() into 
this function if you want.
