    Make yours right, Bunk will "fix" infiniband core. The kernel style
    matters not the subsystem. In Documentation/CodingStyle

    Chapter 13: Allocating memory

    The kernel provides the following general purpose memory allocators:
    kmalloc(), kzalloc(), kcalloc(), and vmalloc(). Please refer to the API
    documentation for further information about them.

    The preferred form for passing a size of a struct is the following:

    p = kmalloc(sizeof(*p), ...);

    The alternative form where struct name is spelled out hurts readability and
    introduces an opportunity for a bug when the pointer variable type is changed
    but the corresponding sizeof that is passed to a memory allocator is not.

    Casting the return value which is a void pointer is redundant. The
    conversion from void pointer to any other pointer type is guaranteed by
    the C programming language.
