Should we move this lock outside of the loop?

I figured to put it inside the loop since if it locks outside the loop instead of for each transaction, it might cause more lock contention

defer s.storageState.Unlock()

rt.SetContextStorage(ts)
ts, err := s.storageState.TrieState(&head.StateRoot) //nolint
if err != nil {
return err
}

// validate each transaction
externalExt := types.Extrinsic(append([]byte{byte(types.TxnExternal)}, tx...))
val, err := rt.ValidateTransaction(externalExt)
if err != nil {
logger.Debug("failed to validate transaction", "err", err)
continue
}
rt.SetContextStorage(ts)

// validate each transaction
externalExt := types.Extrinsic(append([]byte{byte(types.TxnExternal)}, tx...))
val, err := rt.ValidateTransaction(externalExt)
if err != nil {
logger.Debug("failed to validate transaction", "err", err)
return nil
}

// create new valid transaction
vtx := transaction.NewValidTransaction(tx, val)

// push to the transaction queue of BABE session
hash := s.transactionState.AddToPool(vtx)
logger.Trace("added transaction to pool", "hash", hash)

// create new valid transaction
vtx := transaction.NewValidTransaction(tx, val)
// find tx(s) that should propagate
if val.Propagate {
toPropagate = append(toPropagate, tx)
}

// push to the transaction queue of BABE session
hash := s.transactionState.AddToPool(vtx)
logger.Trace("Added transaction to queue", "hash", hash)
return nil
}()

// find tx(s) that should propagate
if val.Propagate {
toPropagate = append(toPropagate, tx)
if err != nil {
return false, err
}
}

msg.Extrinsics = toPropagate

return len(msg.Extrinsics) > 0, nil
}
