Something similar had been discussed a while ago (I don't remember whether you'd been on Cc, though). E.g. ceph and lustre would benefit from having such method (proposed name was ->d_init(), seeing that it's not always just an allocation). The subtle part is barriers and I would really like to see a proof that you don't need any.
