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

92 James Bottomley <JBottomley@Parallels.com>
99 Josef Bacik <jbacik@fusionio.com>
111 David S. Miller <davem@davemloft.net>

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