aufs module build fails with CONFIG_AUFS_DEBUG in linux-source-2.6.31

[Newbie]

SRU Justification:

Impact: Build system change only

Fix: Adding another header file.

Hi all,

   I'm to trying the linux-source-2.6.31 and facing problems doing this
I copied and pasted the console message what I get here:

Reassigning to the linux package, as it's their aufs code copy.

This bug is not present in the upstream AUFS tree, nor in Lucid (see d3a3a7e195364ffe370478f3b05f1b7cb83c6ad3)

[Mirsal Ennaime (mirsal-ennaime)]

Thank you for taking the time to report this bug and helping to make Ubuntu better.
If you didn't mean to build aufs with debugging support, you should remove CONFIG_AUFS_DEBUG from your kernel configuration.

Location:
     -> Ubuntu Supplied Third-Party Device Drivers
       -> Aufs (Advanced multi layered unification filesystem) support (AUFS_FS [=m])
         -> Debug aufs

Otherwise, you can apply the modifications shown in the attached patch.

Accepted linux into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
