It was posted to list on November 25th (and you even included it in

What´s the git url for the cifs-tree? The one referred to in MAINTAINERS doesn´t seem to work.

I think this warning has lived long enough and needs to go away. Steve
supposedly has a patch that finally makes this change, but it hasn't
been sent to the list yet... Steve?

Re: [RFQ PATCH] cifs: Change default security error message
This has already been changed in the cifs-2.6.git for-next branch.
We had run into problems with Apple Server with ntlmv2 so it took
longer than expected to test it, and it was too late for 3.7 so the
patch to move to ntlmssp encapsulated ntlmv2 which removes this
warning is in cifs-2.6.git and queued for 3.8

[RFQ PATCH] cifs: Change default security error message
Hi!
Connecting with a default security mechanism prompts an KERN_ERROR
output warning to the user that the default mechanism will be changed
in Linux 3.3.
We're now at 3.7, so we either could remove the warning completely
(if the default has been changed), or we could bump the number to
what our current target for the change is.
The below patch changes the cERROR (which turns into a printk with KERN_ERROR)
into a straight printk with KERN_WARNING and changes the text to indicate
that it was changed in 3.3.
I expect that the patch is incorrect and that we should choose
another of the alternative solutions above, but I'd like to get
some input on this.
