config PROC_FS

  	bool "/proc file system support" if EXPERT

  	default y
  	help
  	  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.txt> 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.

  config PROC_SYSCTL

  	default y
  	---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/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.

  
  config PROC_PAGE_MONITOR

  	bool "Enable /proc page monitoring" if EXPERT

   	help
  	  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.
