Hello,Â

I just wanted to submit this as one of the bugs, the one which George assigned to me is still pending(it's a patch series), I will submit that ASAP. As for this bug, if I have incorrectly handled it, can you please point out my mistake, I will correct it and re-submit.Â

Thanks

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

Regards,
Dario
