Subject: [PATCH 0/6] ext4: status extents 

This set is based on the earlier delayed extent tree, but has
been renamed to a "status extent" scheme.  The plan is that the
tree will be expanded to track allocated extents and also
support extent locks.  Thus status extents seemed like a
more appropriate name.

Allison Henderson (6):
  ext4: add two structures supporting status extent tree
  ext4: add operations on status extent tree
  ext4: initialize status extent tree
  ext4: let ext4 maintian status extent trees
  ext4: reimplement fiemap on status extent tree
  ext4: reimplement ext4_find_delay_alloc_range on status extent tree
