Depending on the value of rcfw->cmdq_depth, then this might not cause an issue at runtime. The BITS_TO_LONGS() macro tells us how many longs it take to hold a bitmap. In other words, it divides by the number if bits per long and rounds up. Then we want to take that number and multiple by sizeof(long) to get the number of bytes to allocate. The code here does the multiplication first so the rounding up is done in the wrong place. So imagine we want to allocate 1 bit, then "(1 * 8) / 64 = 1" when we round up. But it should be "(1 / 64) * 8 = 8". In other words, because of the rounding difference we might allocate up to "sizeof(long) - 1" bytes fewer than intended.
