Hi,
I wanted to know why Btrfs is selected as default file system for MeeGo. Following text is copied from Btrfs kernel
Kconfigoption:Btrfs filesystem (EXPERIMENTAL) Unstable disk format
the
Kconfigtext is out of date.

Thanks for the information :)
I am CCing this to linux-btrfs so that someone can take a look at this text and fix this for 2.6.34 release.
Can someone update the btrfs kconfig text which says that this file system is experimental and on disk format is not yet finalized?
Hi everyone,
It is too late for such a change in 2.6.34, Linus announced the final RC this week. But I'll have this queued in my .35 releases.
If meego would like to include a patch for this in their kernel, I'd be happy to send it along.

Hm, I'd consider such a Kconfig file change to be cosmetic only and could be included during the RC series. Anyway, .35 is probably fine too.

If no-one sends a patch, how about:
-----------------
Remove EXPERIMENTAL flag from btrfs and also state that the disk format has indeed been finalized.
