- Fix for btrfs_find_free_objectid · b1785427
  Yan authored Jan 22, 2008
```
btrfs_find_free_objectid may return a used objectid due to arithmetic
underflow. This bug may happen when parameter 'root' is tree root,  so
it may cause serious problems when creating snapshot or sub-volume.

  Chris Mason authored Jan 16, 2008
```
Using ilookup5 during data=ordered writeback could deadlock on I_LOCK.  This
saves a pointer to the inode instead.

- Btrfs: online shrinking fixes · c31f8830
  Chris Mason authored Jan 08, 2008
```
While shrinking the FS, the allocation functions need to make sure
they don't try to allocate bytes past the end of the FS.

nodatacow needed an extra check to force cows when the existing extents are
past the end of the FS.

- Btrfs: Move snapshot creation to commit time · 3063d29f
  Chris Mason authored Jan 08, 2008
```
It is very difficult to create a consistent snapshot of the btree when
other writers may update the btree before the commit is done.

This changes the snapshot creation to happen during the commit, while
no other updates are possible.

- Btrfs: Add data=ordered support · dc17ff8f

```
This forces file data extents down the disk along with the metadata that
references them.  The current implementation is fairly simple, and just
writes out all of the dirty pages in an inode before the commit.

- Properly call btrfs_search_slot while shrinking · 1372f8e6
  Chris Mason authored Jan 04, 2008
```
The shrinking code used btrfs_next_leaf to find the next item, but
this does not cow the blocks it touches.  This fix calls search_slot after
finding the next item to do appropriate cow and balancing.

- Btrfs: Properly handle overlapping extent in shrink_extent_tree · 73e48b27
  Yan authored Jan 03, 2008
```
The patch fixes the overlapping extent issue in shrink_extent_tree.
It checks whether there is an overlapping extent by using
find_previous_extent. If there is an overlapping extent, it setups
key.objectid and cur_byte properly.
