- Added container filesystem to the `ImageFsInfoResponse`. ([#120914](https://github.com/kubernetes/kubernetes/pull/120914), [@kannon92](https://github.com/kannon92))
- Added multiplication functionality to `Quantity`. ([#117411](https://github.com/kubernetes/kubernetes/pull/117411), [@tenzen-y](https://github.com/tenzen-y))

// Let v = [ 4  6 ]^T  be the output gradient (^T = transposed). Then the
// average pool gradient is given by
//    Df^T * v = [ 4/3  4/3  13/3  3 ]^T
// Instead of a matrix-vector-multiplication we can utilize the sparsity and
// structure of Df by using the 3-step approach from above:
// 1. Divide output gradient v by window counts: [ 4/3  6/2 ]^T
// 2. Add appropriate padding: [ 0  0  4/3  0  3  0 ]^T
