Subject: Stable backport of cifs nlink workaround?

Hi,

Is there any chance that 74d290da476f672ad756634d12aa707375d3564d
([CIFS] Provide sane values for nlink) could be backported to the stable
3.2 kernel?

The reason I ask is because if you Using a Debain Wheezy box with a
3.2.41-2+deb7u2 kernel the following is problematic:

Mount a share using cifs from a Windows 2008 machine on to 2008share
Use Samba 3.6 to export the share as //linux/2008share
Using a Windows 2012 machine browse to \\linux\2008share

because the directories will appear to be files to the Windows 2012
machine.

On the Debian box doing
stat 2008share/dir
says
Device: 18h/24d	Inode: 844424932383132  Links: 1

Using a Fedora 20 box with a 3.13.3-201.fc20.x86_64 kernel to do the
same says:
Device: 27h/39d	Inode: 844424932383132  Links: 2

In https://bugzilla.kernel.org/show_bug.cgi?id=52791#c4 Jeff mentions
that if there were demand a RHEL 6 customer could ask for a backport so
it looks like the change is isolated enough to be put into stable...

https://bugzilla.samba.org/show_bug.cgi?id=9346 also talks about the
issue.
