[PATCH 0/3] Add O_DENY* flags to fcntl and cifs

> I suspect that WINE would have the same need

Tricky - Wine needs to enforce this behaviour solely between Wine and
the file server, Trying to muck up non emulated local behaviour would be
a bad mistake.

One way perhaps to look at this is you want some tasks to be able to *opt
in* to this behaviour.

First however I think we need a much better description of the setup that
uses them and why it matters.
