[snip]
This bug is found on upstream 2.6.36 kernel. We ran a 2.6.36 kernel on the online system with 8 Ext4 file systems. 2 of
them are mounted with delayed allocation feature. This warning is only observed on delayed allocation enabled Ext4 file
systems.
This issue is not easy to reproduce, on two servers with 2.6.36 kenrel + ext4, after running 110+ days, the error starts
to appear on kernel log. When check the error log, we found the info format should be fixed, that's how this patch comes.
For the bug mentioned in Robin's patch, we will start another thread to discuss.
Thanks.
Coly Li
