While going through the code of IPC semaphore implementation, I encountered a statement:
new = ipc_rcu_alloc(sizeof(struct kern_ipc_perm *)*newsize +sizeof(struct ipc_id_ary))
I am not able to understand how memory will be allocated by the above statement. Inside the sizeof() operator why do we need "*newsize"? how does size of interprets *newsize?
