And it is used in the following codes. However, > when there is a memory allocation error, kmalloc() fails. Thus null > pointer dereference may happen. And it will cause the kernel to crash. > Therefore, we should check the return value and handle the error. > > Signed-off-by: Gen Zhang <blackgod016574@...il.com> Applied.
