Please use C struct types for the file handles. Take a look at
fs/xfs/linux-2.6/xfs_export.[ch] for an example.

This one will only find inodes when they already are in memory. You
need to something similar to btrfs_lookup minus the btrfs_inode_by_name
call here. In fact it would make a lot of sense to factor that part
of btrfs_lookup out into a btrfs_iget helper that takes a struct
btrfs_key pointer and returns the inode for you.
