[patch 00/43] lguest: Patches for 2.6.24 (and patchbomb test)
Hi all,
These are the patches I'm planning to submit for 2.6.24. Comments
gratefully accepted. Along with the usual cleanups and improvements are Jes'
de-i386-ification patches, and a new "virtio" mechanism designed to be shared
with KVM (and hopefully other hypervisors).
Cheers,
Rusty.
