My stats:

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

(No merge commits counted, next-20170220 was the first linux-next after
the merge window opened.)

Commits in v4.11-rc1 (relative to v4.10): 10960
Commits in next-20170220: 9791
Commits with the same SHA1: 9016
Commits with the same patch_id: 479 (1)
Commits with the same subject line: 68 (1)

(1) not counting those in the lines above.

So commits in -rc1 that were in next-20170220: 9563 87%

[
v4.10-rc1 like this:

Commits in v4.10-rc1 (relative to v4.9): 11455
Commits in next-20161212: 10625
Commits with the same SHA1: 9927
Commits with the same patch_id: 437 (1)
Commits with the same subject line: 25 (1)

(1) not counting those in the lines above.

So commits in -rc1 that were in next-20161212: 10389 90%

And v4.9-rc1 like this:

Commits in v4.9-rc1 (relative to v4.8): 14308
Commits in next-20161004: 13539
Commits with the same SHA1: 12716
Commits with the same patch_id: 485 (1)
Commits with the same subject line: 33 (1)

(1) not counting those in the lines above.

So commits in -rc1 that were in next-20161004: 13234 92%

So this time we have slightly more rebasing and overall more "extra" commits.

Some breakdown of the list of extra commits (relative to next-20170220)

There are also 229 commits in next-20170220 that didn't make it into
v4.11-rc1.

8 viro@zeniv.linux.org.uk
7 arnd@arndb.de
6 varun@chelsio.com
5 sonic.zhang@analog.com
4 realmz6@gmail.com

Some of Andrew's patches are fixes for other patches in his tree (and
have been merged into those).

Top ten commiters:

76 sfr@canb.auug.org.au
20 mchehab@kernel.org
16 steven@ubuntu-virtualbox.(none)
11 dhowells@redhat.com
10 olof@lixom.net
9 luisbg@osg.samsung.com
8 viro@zeniv.linux.org.uk
7 tytso@mit.edu
7 bart.vanassche@sandisk.com
6 mathieu.poirier@linaro.org

Those commits by me are from the quilt series (mainly Andrew's mmotm
tree). The steven@ubuntu-virtualbox.(none) ones are form a very out of
date blackfin tree that has now been removed from linux-next.

Cheers,
Stephen Rothwell
