Xen devel - Jul 2008 - [PATCH] Fix issues when passthrough device is hot-removed from HVM domain.

When passthrough device is hot removed from HVM domain by "xm
pci-detach" command, following issues occur. The patch fixes them.

   - Allocated memory is not deallocated.
   - Unbind interrupt with invalid interrupt pin.
   - MSI-X memory mapped register area is not unmapped.

Thanks.

Thanks for this patch.

However can you please ask your program to stop marking these patches
as if they were opaque binary data attachments ?  That makes it hard
for other people using normal mailreaders to review your changes -
sometimes we even have to save the patch to a file, because your
mailer has tagged it as if it were a binary file like a kernel image
or something.

I don''t know how to achieve this with your mailer, but it''s
possible
that changing the patch filename from `*.patch'' to `*.txt''
will help.

(At a technical level, what I''m complaining about is this MIME data
for the body part containing the patch:
    Content-Type: application/octet-stream;
     name="fix_hot-remove.patch"
    Content-Disposition: attachment;
     filename="fix_hot-remove.patch"
`application/octet-stream'' is wrong and should read
`text/plain'', or
perhaps `text/x-patch'' or something.)

Thanks,
Ian.

Thank you for your kind advice.
I changed the MIME setting.

Thanks.
