Bug#587763: linux-image-2.6.32-5-amd64: scary messages from JBD when manipulating quotas on ext4

[Laurent Bonnaud <bonnaud@iut2.upmf-grenoble.fr>]

Package: linux-2.6
Version: 2.6.32-15
Severity: important


Hi,

here is how to reproduce this bug:

1. set up quotas on an ext4 filesystem
2. use edquota to change the quotas of some user

Actual result: the kernel outputs this scary message:

[  399.792052] JBD: Spotted dirty metadata buffer (dev = sdb1, blocknr =
34816). There's a risk of filesystem corruption in case of system crash.

Expected result: 
 - no scary message
 - no filesystem corruption
 - changed quotas
