 * Similar to regular join but it never starts a transaction when none is

 * running or after waiting for the current one to finish.

 * running or when there's a running one at a state >= TRANS_STATE_UNBLOCKED.

 * This is similar to btrfs_attach_transaction() but it allows the join to

 * happen if the transaction commit already started but it's not yet in the

 * "doing" phase (the state is < TRANS_STATE_COMMIT_DOING).
