ever (see http://neuling.org/linux-next-size.html after today's
linux-next release).

Since you asked ... :-)

This was the second biggest linux-next ever (in terms of commits) the one
before v3.8 was somewhat larger).

(No merge commits counted, next-20130429 was the last linux-next before v3.9)

Commits in v3.10-rc1 (relative to v3.9): 11963
Commits in next-20130429:		 11300
Commits with the same SHA1:		  9708
Commits with the same patch_id:		   885	(1)
Commits with the same subject line:	    91	(1)

(1) not counting those in the lines above.

So commits in -rc1 that were "in" next-20130429:	10684	89.3%
						(down from 90.6% last time)
Commits in -rc1 that were not in next-20120722:		 1279	10.7%

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:

     27 NVMe
     29 xfs
     41 drm
     47 powerpc
     59 rbd
     64 arm
     78 media
     84 mips
     92 SCSI
    101 btrfs

     99 Josef Bacik <jbacik@...ionio.com>
    111 David S. Miller <davem@...emloft.net>

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