5	  This is a virtual file system providing information about the status
6	  of the system. "Virtual" means that it doesn't take up any space on
7	  your hard disk: the files are created on the fly by the kernel when
8	  you try to access them. Also, you cannot read the files with older
9	  version of the program less: you need to use more or cat.
10
11	  It's totally cool; for example, "cat /proc/interrupts" gives
12	  information about what the different IRQs are used for at the moment
13	  (there is a small number of Interrupt ReQuest lines in your computer
14	  that are used by the attached devices to gain the CPU's attention --
15	  often a source of trouble if two devices are mistakenly configured
16	  to use the same IRQ). The program procinfo to display some
17	  information about your system gathered from the /proc file system.
18
19	  Before you can use the /proc file system, it has to be mounted,
20	  meaning it has to be given a location in the directory hierarchy.
21	  That location should be /proc. A command such as "mount -t proc proc
22	  /proc" or the equivalent line in /etc/fstab does the job.
23
24	  The /proc file system is explained in the file
25	  <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
26	  ("man 5 proc").
27
28	  This option will enlarge your kernel by about 67 KB. Several
29	  programs depend on this, so everyone should say Y here.

45	select SYSCTL
46	default y
47	---help---
48	  The sysctl interface provides a means of dynamically changing
49	  certain kernel parameters and variables on the fly without requiring
50	  a recompile of the kernel or reboot of the system.  The primary
51	  interface is through /proc/sys.  If you say Y here a tree of
52	  modifiable sysctl entries will be generated beneath the
53          /proc/sys directory. They are explained in the files
54	  in <file:Documentation/sysctl/>.  Note that enabling this
55	  option will enlarge the kernel by at least 8 KB.
56
57	  As it is generally a good thing, you should say Y here unless
58	  building a kernel for install/rescue disks or your system is very
59	  limited in memory.

61config PROC_PAGE_MONITOR

65 	help
66	  Various /proc files exist to monitor process memory utilization:
67	  /proc/pid/smaps, /proc/pid/clear_refs, /proc/pid/pagemap,
68	  /proc/kpagecount, and /proc/kpageflags. Disabling these
69          interfaces will reduce the size of the kernel by approximately 4kb.
