The only files with i_nlink == 0 that can be linked into the namespace or O_TMPFILE files that have I_LINKABLE. The only think that cares about S_PRIVATE are the security modules (and reiserfs for it's own xattr inodes). So I think setting the flag is a good thing and gets us out of nasty interaction with LSMs, but the commit log could use a little update.
