The first line of the commit should be a short summary, usually preceded by an indication of the area of the code being fixed, like "hw/net/rocker:". Then there should be a blank line, followed by the more detailed description of the change. You can look at the git commit logs for existing commits to get the idea. > Signed-off-by: sohu0106 <sohu0106@126.com> We request that Signed-off-by: lines are your full real name, not a pseudonym or email address; this is because you are stating with this line that it's legally OK for this patch to go into QEMU.
