Comment # 5 on bug 905832 from Takashi Iwai

Can anyone check the kernel in OBS home:tiwai:os13.2-ckt1 project?  This
contains the backports of Ubuntu kernels.  It's just to make sure whether it's
btrfs specific -- a few of backports are related with mmap but rather generic
vfs fixes.

The packages are currently being built and might not be published yet, but you
can download already many of them directly via osc.
