mm.git review status at 7.0-rc6

[Andrew Morton <akpm@linux-foundation.org>]

If anyone wishes to be Bcc:ed on these little missives then drop me a
note and I'll add you to my list, no probs.

mm.git's mm-stable branch contains 358 patches and that's a wrap.  This
is the material I intend to send into Linus in the first week of the
merge window, April 14 seems likely.

The mm-unstable branch presently holds 135 patches.  I'll move some
subset of these into mm-stable after Linus has merged batch #1, so
maybe Apr 17.  I'll ask him to pull this material in the second week,
maybe Apr 20.

mm-new presently holds 10 patches, the aim it to keep this "empty" until
we're all merged up.

I'll be spending the merge window getting dragged around Roman ruins
(please save me) while laptopping over the hotel WiFi.  Responsiveness
will be slight.

People, please let's not see an enormous flood of patches the day after
-rc1 is released?  If you have new non-critical patches then it's best
to send them out when they're ready rather than buffering them up. 
They won't be applied to mm.git and they may not get 100% attention but
it's better this way - spread things out, at least give others a view
of what's coming up.

We still have ~38 unreviewed patches in mm-unstable, listed below.  We
have nearly three weeks to get everything nailed down.

Thanks.
