[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 0/8] lguest
As promised to Andrew, and with much thanks to Andi Kleen for feedback,
this is the new series of lguest patches.
Main change is the move to drivers/lguest (for future non-i386
expansion), but lots of cleanups driven by Andi's feedback and the
documentation effort (which made me examine every line of code).
It's not perfect, but it's definitely useful.
Cheers,
Rusty.
