Re: [Xen-devel] [Patch] for expanding the vbd devices

[Hidetoshi Nishi <nishi.hidetoshi@xxxxxxxxxxxxxx>]

Hi all.

Thank you for applying the patch.

I have one question.

The patch I sent includes extending the timer of device creation.
But this change is not merged, it has some problem.

If you have some comment, please let me know.


Thanks a lot,                                    Nishi
