No problem at all, I agree that your suggestions make the code easier
to read. Changes since last push:
- Fix vfs_default copy chunk async function order.
- Shorten tevent_req_nterror() and tevent_req_nomem() error paths. This
  doesn't catch all status checks prior to tevent_req_nterror().

Cheers, David
