But then you're not closing xs_fd, is that ok? (I'm asking, because I
am not at all a xenstore expert, but, FWIW, it does not feel right to
me).

Most of this (except the first bullet point, perhaps), and especially
the Signed-off-by (it's 'Signed-off-by:', not 'Signed-off') tag goes in
the patch changelog.

In fact:
 - this looks like a cover letter for a patch series, but there is 
   only one patch in this case. Usually, when there is only one patch, 
   you don't need a cover letter (there are exceptions, but I don't 
   think this qualifies);
 - cover letters, no matter whether for series or single patches, do 
   not become part of the source tree, when the patch (series) is 
   committed. That is why, information about the patch 
   content/design/etc. and the tags must live in the changelog. If you 
   do like this, someone looking at `git log' wouldn't see it.

Regards,
Dario
