X-Git-Tag: archive/raspbian/4.14.0+80-gd101b417b7-1+rpi1^2~63^2~953 X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=6e99520bf47f9de2dc59b9fbbc5f932fca3a8086;p=xen.git x86/save: reserve HVM save record numbers that have been consumed... ...for patches not (yet) upstream. This patch is simply adding a comment to reserve save record number space to avoid the risk of clashes between existent downstream changes made by Amazon and future upstream changes which may be incompatible.
