btrfs: fixes for kobject changes in mainline
Here's a patch against the unstable tree that gets the code to build against Linus's current tree (2.6.24-git12). This is needed as the kobject/kset api has changed there. I tried to make the smallest changes needed, and it builds and loads successfully, but I don't have a btrfs volume anywhere (yet) to try to see if things still work properly :) Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
