The ZFS code base is stable, the problem is the VFS interface in Linux and that 
applies to all filesystems....

The ZFS developers have been forced by Sun to put their home directoriers on 
ZFS in 2001. Does this apply to BTRFS too?

This is not a problem as nobody encourages you to put ZFS into toys or phones.
With the typical amout of RAM in today's machines, ZFS is happy.
