Hi Dave,

I couldn't get this pull by John this week, he's been unresponsive.
We would love to see this code in the 3.4 kernel (not sure if this would be
possible if Linus do not release the -rc7, there are important fixes 
in the pull request, such as a fix to a regression that was breaking bluetooth
keyboards.

Please let me know if you have any problems with this! I checked this code for
coding style issues too. Thanks.

Well, I do apologize for my lack of responsiveness.  My employer saw
fit to have me (figuratively) locked in a room with no email access all
week, with me getting home rather late in the evenings and returning
early each morning.  I would have liked to have stayed awake for
hours each night catching-up, but I just didn't have the strength. :-(

With that said, I'm not at all sure that this batch of fixes is
appropriate for this late in the release cycle.  Normally at this
point I would expect to see "regression cause by commit 1234" or
"this common action results in this crash", all fixed by one-liners
wherever possible.  This batch is more like "causes some problems",
or "needs to be different" -- neither of which sound urgent enough
to be worth requesting delays in Linus's release schedule.

In my point of view there are two commits there that are really necessary:

Gustavo Padovan (2):
      Bluetooth: report the right security level in getsockopt

Johan Hedberg (2):
      Bluetooth: mgmt: Fix device_connected sending order

They fix a userspace breakage caused by:

Author: Marcel Holtmann [off-list ref]
Date:   Mon Feb 20 21:24:37 2012 +0100

    Bluetooth: Always enable management interface
    
    The management interface API has reached stable version 1.0 and thus
    it can now be always enabled. All future changes will be made backwards
    compatible.

This cause no crash, but it make bluetooth keyboards stop to work with Linux.
This a serious breakage IMO. I really would like to see at least these two
patches in. The other fixes can wait.
