  Hello,

  so I have created this patch set which removes ext3 driver (and some related support
code) from the kernel. See changelog of patch 2/3 for more details. If noone objects,
I will queue the series in my tree for the next merge window.

Jens, are you OK with me merging patch 3/3 or do you want me to send it to you once
the first two patches get merged?

Ted, this also touches ext4 driver so that it always handles ext3 filesystems so ack
from you would be nice.

This means some ext3-specific kludges in mm/ could be dropped.
Like page cleanup in try_to_free_buffers() and couple in vmscan.

Almost. There are still some cases (like block device mappings or even
standard inode mappings in ext4 data=journal mode) where the page cleanup
hack is needed. See
https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg933319.html

Both issues look fixable although with block device mappings it won't be
trivial.
