If the user provides a value of "0" for "count", then kmalloc would not return NULL, but also there will be a memory block of "zero" size. This can lead to buffer overflows. Also trying to access invalid memory will cause kernel crashes. Ensure to check that the number of bytes to be written is non-zero. If zero, return invalid input.
