#     nfp: Prefer struct_size over open coded arithmetic
#     
#     As noted in the "Deprecated Interfaces, Language Features, Attributes,
#     and Conventions" documentation [1], size calculations (especially
#     multiplication) should not be performed in memory allocator (or similar)
#     function arguments due to the risk of them overflowing. This could lead
#     to values wrapping around and a smaller allocation being made than the
#     caller was expecting. Using those allocations could lead to linear
#     overflows of heap memory and other misbehaviors.
#     
#     So, use the struct_size() helper to do the arithmetic instead of the
#     argument "size + count * size" in the kzalloc() function.
#
