As called in the other patch to expose policy brief via selinuxfs (sel_read_policybrief), the intent is to provide the caller with the length of the string returned. Or should I set *len to policy brief_len here, and just make the caller aware that the returned length is in fact the length of the buffer (i.e. including terminating NUL byte)?
