  Btrfs: online shrinking fixes · c31f8830
  由 Chris Mason 提交于 1月 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
  由 Chris Mason 提交于 1月 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
  由 Chris Mason 提交于 1月 08, 2008
```
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
  由 Chris Mason 提交于 1月 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
  由 Yan 提交于 1月 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.

is under snapshot.

  Off by one fix for btrfs_drop_extents · 6e3b9666
  由 Yan 提交于 12月 14, 2007
```
One of my old patches introduces a new bug to
btrfs_drop_extents(changeset 275). Inline extents are not truncated
properly when "extent_end == end", it can trigger the BUG_ON at
file.c:600.  I hope I don't introduce new bug this time.
