As usual, the executive friendly graph is at
http://neuling.org/linux-next-size.html :-)

(No merge commits counted, next-20130701 was the linux-next based on v3.10)

Commits in v3.11-rc1 (relative to v3.10): 9494
Commits in next-20130701:		  8929
Commits with the same SHA1:		  7670
Commits with the same patch_id:		   759	(1)
Commits with the same subject line:	    55	(1)

(1) not counting those in the lines above.

So commits in -rc1 that were "in" next-20130701:	8484	89.4%
			(essentially unchanged from 89.3% last time)
Commits in -rc1 that were not in next-20120722:		1010	10.6%

Pretty good, but it would be still nice to figure out where the last lot
came from.  I have the "git log --oneline --no-walk" list if someone
wants them.

Some breakdown of that list:

Top ten first word of commit summary:

     80 btrfs
     41 arm
     35 [scsi]
     32 net
     28 drm/exynos
     25 perf
     25 drm/radeon/dpm
     19 vxlan
     17 input
     16 tracing

     24 Dave Airlie <airlied@redhat.com>
     23 Thomas Gleixner <tglx@linutronix.de>
     23 Arnaldo Carvalho de Melo <acme@redhat.com>

Quite a few of these could be bug fixes (especially DaveM's).

There are also 444 commits in next-20130701 that didn't make it into v3.11-rc1.

Top twelve first word of commit summary:

     66 arm

     10 Joern Engel <joern@logfs.org>
     10 Daniel Vetter <daniel.vetter@ffwll.ch>

Some of Andrew's patches are fixes for other patches in his tree (and
have been merged into those).  Paul's patches are the __cpuinit removal
series that should be applied right after -rc1.

     11 Rafael J. Wysocki <rafael.j.wysocki@intel.com>
 
Well, that's embarrasing :-)  Those commits by me are from the quilt
series (including Andrew's mmotm tree).

Some of the above will have been merged into other patches or replaced, I
guess.
