Hello,

Kernels: 2.6.34 to HEAD. Using ~amd64 Gentoo. All my filesystems
except /boot are btrfs.

btrfsck says I have a corrupted btrfs filesystem on my machine, and I
see this message in dmesg when mounting the filesystem (in
fs/btrfs/disk-io.c:284):

parent transid verify failed on 48136192 wanted 16424 found 16420

But there is something strange:

* this message only appears twice when running 2.6.34;
* it fills my dmesg (several tens of thousands of times a second -
printk_ratelimit() triggers to suppress the vast majority of them)
when running HEAD.

After a quick git log v2.6.34.. -- fs/btrfs, I found commit
5bdd3536cbbe2ecd94ecc14410c6b1b31da16381, which I reverted: HEAD now
"behaves" like 2.6.34, dmesg-wise. Unintended side effect?
