As issue #45, we should use preallocation for preconditioners. I don't know if we can update variants.jl this time, M is a keyword argument.
Maybe we could move preallocated_LinearOperator and preallocated_symmetric_LinearOperator functions in LinearOperators?

Yes, we should certainly have preallocated operators in LinearOperators.
