kbleds: Replace magic with driver_name

b9b37fc39f kbleds: Replace magic with driver_name 
Since the commit 5052df99d3bc ("tty: remove TTY_DRIVER_MAGIC") [1],
the magic field no longer exists in the tty_driver. Instead of
printing the magic field, use the driver_name field.

Peter Lin
421b9b04fe 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.

d2d54ca639 Remove sleep_on family 
Since the commit b8780c363d80 ("sched: remove sleep_on() and friends
"), the description about sleep_on is incorrect and the example code has
been fixed by replacing it with wait_event family. Let's also fix the
description to match the corrected code.

e62dff0df4 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()
 2022-12-25 20:24:10 +08:00
linD026
78e3e062c4 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().
