Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

|

This is a virtual file system providing information about the status
|
|
of the system. "Virtual" means that it doesn't take up any space on
|
|
your hard disk: the files are created on the fly by the kernel when
|
|
you try to access them. Also, you cannot read the files with older
|
|
version of the program less: you need to use more or cat.
|
|
|
|
It's totally cool; for example, "cat /proc/interrupts" gives
|
|
information about what the different IRQs are used for at the moment
|
|
(there is a small number of Interrupt ReQuest lines in your computer
|
|
that are used by the attached devices to gain the CPU's attention --
|
|
often a source of trouble if two devices are mistakenly configured
|
|
to use the same IRQ). The program procinfo to display some
|
|
information about your system gathered from the /proc file system.
|
|
|
|
Before you can use the /proc file system, it has to be mounted,
|
|
meaning it has to be given a location in the directory hierarchy.
|
|
That location should be /proc. A command such as "mount -t proc proc
|
|
/proc" or the equivalent line in /etc/fstab does the job.
|
|
|
|
The /proc file system is explained in the file
|
|
<file:Documentation/filesystems/proc.rst> and on the proc(5) manpage
|
|
("man 5 proc").
|
|
|
|
This option will enlarge your kernel by about 67 KB. Several
|
|
programs depend on this, so everyone should say Y here.

After kernel panic, device drivers can collect the device
|
|
specific snapshot of their hardware or firmware before the
|
|
underlying devices are initialized in crash recovery kernel.
|
|
Note that the device driver must be present in the crash
|
|
recovery kernel's initramfs to collect its underlying device
|
|
snapshot.
|
|
|
|
If you say Y here, the collected device dumps will be added
|
|
as ELF notes to /proc/vmcore. You can still disable device
|
|
dump using the kernel command line option 'novmcoredd'.

help
|
|
The sysctl interface provides a means of dynamically changing
|
|
certain kernel parameters and variables on the fly without requiring
|
|
a recompile of the kernel or reboot of the system. The primary
|
|
interface is through /proc/sys. If you say Y here a tree of
|
|
modifiable sysctl entries will be generated beneath the
|
|
/proc/sys directory. They are explained in the files
|
|
in <file:Documentation/admin-guide/sysctl/>. Note that enabling this
|
|
option will enlarge the kernel by at least 8 KB.
|
|
|
|
As it is generally a good thing, you should say Y here unless
|
|
building a kernel for install/rescue disks or your system is very
|
|
limited in memory.

Various /proc files exist to monitor process memory utilization:
|
|
/proc/pid/smaps, /proc/pid/clear_refs, /proc/pid/pagemap,
|
|
/proc/kpagecount, and /proc/kpageflags. Disabling these
|

interfaces will reduce the size of the kernel by approximately 4kb.

this interface. For example, rkt is such a piece of software.
