How to see changelogs for a particular module in kernel

Question

Hello, I want to know how to see the changelogs or commit messages for a module in the kernel. Actually i modified virtio_net in kernel2.6.26. Now the virtio_net in 2.6.34 seems to be lot different from the one in 2.6.26. There should be some git commit messages or changelogs for the different versions of virtio_net. I want to know the progressive difference in features for the module in 2.6.26 and 2.6.34. How to do that? Thank you...

Thanks, Bala

First, install git and clone the kernel tree:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Now you can use git log on an file(s) or directory.

git log drivers/net/virtio_net.c
