Hi Liang, I see you are learning how to send a patch. It's a good thing. I don't know if the idea of your patch will be accepted but here are more tips about formatting: - You should use checkpatch.pl from kernel.org and fix the most important issues - The commit log should be wrapped to avoid long lines - The title is important. You didn't update it for vfio. And there should be no point at the end of the title. - You should use your real name in Signed-off-by. - You should annotate each new version to show the changes
See http://dpdk.org/dev#send and https://www.kernel.org/doc/Documentation/SubmittingPatches Looking at other submissions could be inspiring also. Thanks -- Thomas
