Subject: [RFC PATCH v2 0/4] remove buffer heads from ext2

Hi all,

This series is an effort to begin removing buffer heads from ext2. 
The first patch introduces the bulk of the new buffer cache code, while
the rest of the patches split up changes to each part of the fs for
easier testing.

This is still a work in progress, and there are a couple more things on
my todo list:
- finish removing buffer heads from xattrs, inode allocation, etc
- implement a buffer cache shrinker
- fix various locking issues

Comments and feedback appreciated!

  ext2: remove buffer heads from superblock
  ext2: remove buffer heads from group descriptors
  ext2: remove buffer heads from quota handling
  ext2: remove buffer heads from block bitmaps
