Yeah, sorry, I forgot to add a "From:Wengang Wang 
<wen.gang.wang@oracle.com>" in my guilt.
That way, it will generate the commit with Author of wengang wang 
automatically. Since this patch only
includes about 19 lines of change, and I changed about 5-6 lines, the 
author should be him.

As for the 2nd one, his original patch has this diffstat:
fs/ocfs2/alloc.c | 47 +++++-----
include/trace/events/ocfs2.h | 202 
++++++++++++++++++++++++++++++++++++++++++
2 files changed, 224 insertions(+), 25 deletions(-)

My patch has

fs/ocfs2/alloc.c       |  165 +++++++++--------
fs/ocfs2/ocfs2_trace.h |  485 ++++++++++++++++++++++++++++++++++++++++++++++++
2 files changed, 573 insertions(+), 77 deletions(-)

So I guess the author should be me(What's more, I have changed some of 
his modifications also.)?
Or I should leave his patch there with his sob, while adding a new patch 
of mine?
