- Btrfs: Defrag only leaves, and only when the parent node has a single objectid · a6b6e75e
  Chris Mason authored Oct 15, 2007
```
This allows us to defrag huge directories, but skip the expensive defrag
case in more common usage, where it does not help as much.

Cache block group was overly complex and missed free blocks at the very start

Btrfs: Find and remove dead roots the first time a root is loaded. · 5ce14bbc

Chris Mason authored Sep 11, 2007

Dead roots are trees left over after a crash, and they were either in the
process of being removed or were waiting to be removed when the box crashed.
Before, a search of the entire tree of root pointers was done on mount
looking for dead roots. Now, the search is done the first time we load
a root.

This makes mount faster when there are a large number of snapshots, and it
enables the block accounting code to properly update the block counts on
the latest root as old versions of the root are reaped after a crash.

Btrfs: [PATCH] extent_map: add writepage_end_io hook · 0e2752a7

Christoph Hellwig authored Sep 10, 2007

XFS updates the ondisk inode size only after the data I/O has finished,
so it needs a hook when the writepage end_bio handler has finished.

Might not be worth applying as-is as the per-page callback is very
ineffcient.  What XFS really wants is a callback when writeout of a
whole extent has completed.  This delayed i_size updates scheme might
be worthwile for btrfs aswell, btw.
