Miao,

I was trying out your patch on scalability testing for BTRFS on v3.3
kernel.
http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg14930.html

However, I ran into a lot of warnings (see the dmesg below).  Wonder if
you have a more up to date version of this patch?

In addition, I have to do this modification to fix a warning in your
original patch.

diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c

        }
        return ret;
 }

Thanks.
Tim
