Linux: Btrfs, File Data and Metadata Checksums

,----[ Quote ]
| 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".
