Btrfs Merged in Linux 2.6.29 0

Looks like Btrfs made it into 2.6.29. Which is pretty sweet because as Btrfs stabilizes it means that a large future port isn’t necessary. What’s Btrfs? It’s a compelling ZFS alternative for Linux designed to work with Linux from day zero (as opposed to being ported from Open Solaris). The most compelling feature for me [...]
