Introduce static key in optimizations section
...
This patch introduces static key technique and adds a kernel module
to demostrate how to use static key to optimize an almost unlikely
branch, the module can interact with userspace thru a character device.

been fixed by replacing it with wait_event family. Let's also fix the
description to match the corrected code.

treewide: Clean up the headers
...
The rule of thumb is to include the headers we are the direct user of.
In particular, if we need an atomic API, we include <linux/atomic.h>.
On the other hand we should not use headers for no reason. In particular,
if we are not doing any IRQ job, why is the <linux/irq.h> included?

syscall: Use openat() instead of open()
...
Since sys_open is deprecated and some architectures don't support it.
We switch the implementation to sys_openat.
Moreover, in some architectures like x86-64, the prototype of syscall,
for example, openat(), might have been changed to struct pt_regs [1]
but we cannot promise that so support the two types
(sys_openat and pt_regs).
Also, to prevent other untraced tasks print out the information, add
the uid checking in our_sys_openat().

Fix dereference NULL pointer with proc_lseek
...
Since the operations are static storage duration, the pointer in
operation structures will initialize with NULL. But, the kernel
doesn't check whether the pointer is NULL or not when calling it.
