advfs and btrfs

Just now I read an email in my btrfs mailing list about the opensourcing (GPL v2), by HP, of their filesystem ADVFS. Its very interesting to see what will be oracle’s response to this. Will they ever think that this btrfs venture is a waste ? I’m not terribly sure what would be running in their minds at the moment.

The reporter, Jeff Schroeder has nicely described things as quoted below. Looking at that made me feel that it might not be a waste. But what’s the point of having two very similar filesystems in the kernel ?

Would it make sense to look at using any of the code from this in btrfs, or would it be easier to re-implement it all over again? Even though filesystems ported from other Posix operating systems to Linux (Ever looked at XFS code) can be ugly, this might be a way to accelerate btrfs development. If nothing else, it might be interesting to see how HP solved problems btrfs will soon be solving.

Interesting read..
