Out of Date Project Ideas on Btrfs

[nick]

Greetings All,
I have been searching for work related to the btrfs file system. I am wondering if there is any that is still
valid on the Project Ideas page of the wiki as most of it seems out of date to me. The only one that seems to
be still valid is the Rename syscall new parameters needing to be  supported by btrfs as most of the others including fs_info rather then root object to certain functions as parameters  seem very out of date to me.
Thanks Nick
