Hi!

I have a broken btrfs unable to mount because it is unable to find the tree root. Using find-root I find the following:

Well block 14102764707840 seems great, but generation doesn't match, have=109268, want=109269

Because the filesystem was last in use with a pre 3.2-kernel I am unable to use mount -o recovery, but restore seems to work when I specify the previous tree-root. My problem is however that the btrfs is so large I have nowhere to temporarily put all the files. I am currently running kernel 3.5. Does mount have an option to manually tell it to use the tree root at block 14102764707840?
