  Btrfs: Split the extent_map code into two parts · d1310b2e
  由 Chris Mason 提交于 1月 24, 2008
```
There is now extent_map for mapping offsets in the file to disk and
extent_io for state tracking, IO submission and extent_bufers.

The new extent_map code shifts from [start,end] pairs to [start,len], and
pushes the locking out into the caller.  This allows a few performance
optimizations and is easier to use.

A number of extent_map usage bugs were fixed, mostly with failing
to remove extent_map entries when changing the file.

  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.

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.

  Btrfs: Add full_scan parameter to find_search_start · 5e5745dc
  由 Yan 提交于 11月 16, 2007
```
This patch adds a new parameter 'full_scan' to 'find_search_start',
thereby 'find_search_start' can know whether 'find_free_extent' is in
full scan phrase. I feel that 'find_search_start' should skip calling
'btrfs_find_block_group' when 'find_free_extent' is in full scan
phrase. In my test on a 2GB volume, Oops occurs when space usage is
about 76%. After apply the patch,  Oops occurs when space usage is
near 100%.
