This group of patches removes all DPRINT from hv_vmbus.ko. It is divided in several patches due to size. All DPRINT calls have been removed, and where needed have been replaced with pr_XX native calls. Many debug DPRINT calls have been removed outright. The amount of clutter this driver prints has been significantly reduced. Signed-off-by: Hank Janssen <hjanssen at microsoft.com>

1) Example code: old libc headers don't have SIOCBRADDIF, and old zlibs don't have gzdirect() -- it's a sanity check anyway. 2) Some people don't build in their source directories, so .config isn't there (thanks to Tony Breeds <tony@bakeyournoodle.com>). 3) Point out that guest and host kernel are usually the same. 4) Set the "no checksum" option on the

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

Hi all, I've been working on lguest64 and in order to do this, I had to move a lot of the i386 specific out of the way. Well, the lguest64 port is still not ready to display, but before Rusty makes too many changes I would like this in upstream so I don't have to keep repeating my changes :-) So this patch series moves lguest32 out of the way for other archs. -- Steve

Several DPRINTS are remaining that will be cleaned up in my next set of patches. They deal with printing out certain debugging that will be implemented slightly differently.
