| Chris Mason announced an early alpha release of his new Btrfs
| filesystem, "after the last FS summit, I started working on a new
| filesystem that maintains checksums of all file data and metadata." He
| listed the following features as "mostly implemented": "extent based file
| storage (2^64 max file size), space efficient packing of small files,
| space efficient indexed directories, dynamic inode allocation, writable
| snapshots, subvolumes (separate internal filesystem roots), checksums on
| data and metadata (multiple algorithms available), very fast offline
| filesystem check".
