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.



thanks,
