[Btrfs-users] btrfs questions..

[Voni Hakau]

Hello !

I'm very interested in btrfs development and I have general questions about it.
Please accept my apologizes if they are dumb as I'm new to this area,
and I just want to learn..

1. Like the btrfs name implies (b-trees fs..) I guess that it works basically
like WAFL (and ZFS), is that right ?

2. Are there any big differences between btrfs-wafl-zfs or only small ones ?

3. NetApp claims that ZFS has infringed a set of their patents. They say that
"ZFS was a conscious reimplementation of their WAFL filesystem". What about
btrfs ? isn't there a risk for a similar lawsuit against btrfs' community ?

4. What about Solid State disks ? Assuming that SSD is the future, will btrfs
be able to lead even in front of new SSD requirements/limitations/advantages ?

Thank you all in advance,
Voni.
