Note: I'm seeing this warning (Dirtiable inode bdi default != sb bdi)
when I moved from 2.6.36-rc3 to 2.6.36-rc6, using ext4 as a root
partition, and running mke2fs and e2fsck on ext2, ext3, and ext4 file
systems.  So I'm seeing this as a known regression from rc3 to rc6.
Maybe it's different bug with ext4, but in any case, it's highly
annoying.

Thanks for the info.  I wonder who should see this report.

Andrew, do you know whose area that is?

Oops, correction, the correct warning that I'm seeing is:

[Tejun Heo]

(cc'in Jan and quoting the whole body for him)

Jan, any chance this is caused by the recent bdi change?

  Yes, it's caused by one of my fixes. It's harmless (the warning I've

- http://lkml.org/lkml/2010/9/29/76. I hope he'll push it soon.

Jens is the writeback maintainer, so he will have to pick it up.
