[PATCH 0/5] lguest feedback tidyups
Hi all,
Gratefully-received recent feedback from CC'd was applied to excellent
effect (and the advice from Matt Mackall about my personal appearance is
best unrequited).
The patch is split in 5 parts to correspond with the 9 parts Andrew
sent out before, but here's the summary:
1) Sparse (thanks Christoph Hellwig):
- lguest_const can be static now
- lguest.c should include

[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.
