We are trying to get rid of all multiplications from allocation functions to prevent integer overflows. Here the multiplications are probably safe, but using kcalloc() is more appropriate and improves readability. It is also safer. This series contains a few patches with these fixes. Part of the Kernel Self Protection Project efforts. Links below have more details.
