Re: [Xen-devel] [PATCH v6 00/24] Xenstore stub domain

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

Are these tools and mini-os changes going to be committed, or do you
have further comments to address? The hypervisor changes went in on
1/28, and Ian's (#8) went in on 1/31; I haven't seen any comments
since 1/30.
