- Btrfs: Tune the automatic defrag code · 5708b959
  Chris Mason authored Oct 25, 2007
```
1) Forced defrag wasn't working properly (btrfsctl -d) because some
cache only checks were incorrect.

2) Defrag only the leaves unless in forced defrag mode.

3) Don't use complex logic to figure out if a leaf is needs defrag

- Btrfs: Fix for insert_inline_extent to handle offset != 0 · 18f16f7b
  Yan authored Oct 25, 2007
```
This modifies inline extent size calculation, so that
insert_inline_extent can handle the case that parameter 'offset' is
not zero; it also a few codes to zero uninitialized area in inline
extent.

- Btrfs: Fix split_leaf to detect when it is extending an item · cc0c5538
  Chris Mason authored Oct 25, 2007
```
When making room for a new item, it is ok to create an empty leaf, but
when making room to extend an item, split_leaf needs to make sure it
keeps the item we're extending in the path and make sure we don't end up
with an empty leaf.

- Btrfs: Optimize csum insertion to create larger items when possible · f578d4bd
  Chris Mason authored Oct 25, 2007
```
This reduces the number of calls to btrfs_extend_item and greatly lowers
the cpu usage while writing large files.

```
Just use kobject_set_name(), that works in all kernels (I think...).
Kernels newer than 2.6.23 currently fail with:

- Btrfs: KM_IRQ0 usage in end_io handling · bbf0d006
  Jens Axboe authored Oct 19, 2007
```
endio handling is typically called with interrupts disabled, but can
also be called with it enabled. So save interrupts before using KM_IRQ0
to be completely safe.

It now returns void and it is never called for partial completions, so
the bio->bi_size check must go.
