XenServer configurations that advertise the multi-page ring extension, but only allow a single page of ring space. sys/dev/xen/blkfront/blkfront.c: If only one page of ring space is being used, do not publish in the XenStore the number of pages in use (1), via either of the supported multi-page ring extension schemes. Single page operation is the same with or without the ring-page extension being negotiated. Relying on the legacy behavior avoids an incompatible difference in how the two ring-page extension schemes that are out in the wild, deal with the base case of a single page. The Amazon/Red Hat drivers use the same XenStore variable as if the extension was not negotiated. The Citrix drivers assume the new ring reference XenStore variables will be available Reported by: Oliver Schonefeld <schonefeld@ids-mannheim.de> MFC after: 3 days |
