I think that 1-2 should go into 2.6.35 directly, and 3 for .36 with
a stable backport as well. Agree?

Good, that is what I queued up. I haven't pushed out the updated
for-linus yet, since I asked Linus to pull it this morning.

According to Tim's report on lkml
(http://lkml.org/lkml/2010/6/25/280),
cc56f7de7f00d188c7c4da1e9861581853b9e92f caused a regression.
cc56f7de7f00d188c7c4da1e9861581853b9e92f is present in 2.6.33 and in
2.6.34 hence the fix should be backported into -stable.

According to http://bugs.launchpad.net/bugs/588861, the patch "splice:
direct_splice_actor() should not use pos in sd" fixes the regression.

However this:

commit 4f9078afb4e083e033aafbbfabe729cb3832aa42
Author: Changli Gao <xiaosuo(a)gmail.com>
Date: Tue Jun 29 13:09:18 2010 +0200

splice: direct_splice_actor() should not use pos in sd

went into mainline without a cc:stable tag.
