Hoppin out the grave
boomboom hello eveyrone
I hopped off the plane at LAX
With a dream and my cardigan
Welcome to the land of fame excess (Woah)
Am I gonna fit in?
Jumped in the cab, here I am for the first time
Look to my right, and I see the Hollywood sign
This is all so crazy
Everybody seems so famous
My tummy's turnin' and I'm feelin' kinda homesick
Too much pressure and I'm nervous
That's when the taxi man turned on the radio
And a JAY-Z song was on
And a JAY-Z song was on
And a JAY-Z song was on
So I put my hands up
They're playin' my song, the butterflies fly away
I'm noddin' my head like, "Yeah"
Movin' my hips like, "Yeah"
Got my hands up, they're playing my song
I know I'm gonna be okay
Yeah, it's a party in the U.S.A.
Yeah, it's a party in the U.S.A.

Hello there gentleman
Mc Burberry or Devvo
If you're not last, then you're first.
In the Linux kernel, every process is represented by a task_struct data structure. This structure contains all the information about a process. One of the fields in the task_struct is a pointer to the parent process. This parent pointer is useful for several reasons:
Process Termination: When a process terminates, it becomes a "zombie" process. The kernel keeps the task_struct around so that the parent process can retrieve the child's exit status. Once the parent has done this (using the wait() system call or a variant), the task_struct is deallocated. If the parent pointer weren't stored in the task_struct, the kernel wouldn't know which process should receive the exit status.
Process Hierarchy: Linux processes are organized in a hierarchical structure, similar to a tree. Each process has exactly one parent, which is the process that created it (with the fork() system call, for example). The parent pointer allows the kernel to traverse this hierarchy. This is useful for sending signals to a group of related processes, among other things.
Resource Accounting: The parent pointer can be useful for keeping track of resource usage. For example, the kernel might want to attribute the CPU time used by a child process to its parent.
Security and Permissions: Parent and child processes often have similar permissions, and the parent-child relationship can be used in determining process capabilities.
Note that the parent pointer actually points to the process that the kernel considers the parent, which is not necessarily the process that created this one. For example, if the parent process terminates before the child, the child is adopted by init (or another process in modern Linux systems), and the parent pointer is updated to reflect this.
