Hi Stephen,

thank you for a statistical overview.
It should be interesting and document the Linux-next development.
Especially what came in from last -next release (release before
v4.0-rc1) into v4.0-rc1 - as you write this was next-20150209.

Is that a typo next-20*14*0804?

How did you generate your statistcs (number of commits, top-ten, etc.)?
Thorsten is doing a fantastic job by explaining what is going on in
the Linux-kernel development in his "Kernel-Log" [1] article series
(German). On the last page he describes how he extracted the "numbers"
(please see [2]).
May have a look at it?

Personally, I don't like any of Linus' -rc1 release announcement (but
I read them).
What are the pearls - what is "worth mentioning" - what new stuff is
worth testing (scripts/diffconfig last-stable-config
latest-rc1-config)?
As someone interested in Linux-kernel I expect to get these
informations more "user-friendly".
( IMO, It is irresponsible that user walk through all commits or
merge-commits. )

As a conclusion:
I am interested in such statistics and thank you for this email.

Thanks.
