|
* sysctl.c: General linux system control interface
|
|
*
|
|
* Begun 24 March 1995, Stephen Tweedie
|
|
* Added /proc support, Dec 1995
|
|
* Added bdflush entry and intvec min/max checking, 2/23/96, Tom Dyas.
|
|
* Added hooks for /proc/sys/net (minor, minor patch), 96/4/1, Mike Shaver.
|
|
* Added kernel/java-{interpreter,appletviewer}, 96/5/10, Mike Shaver.
|
|
* Dynamic registration fixes, Stephen Tweedie.
|
|
* Added kswapd-interval, ctrl-alt-del, printk stuff, 1/8/97, Chris Horn.
|
|
* Made sysctl support optional via CONFIG_SYSCTL, 1/10/97, Chris
|
|
* Horn.
|
|
* Added proc_doulongvec_ms_jiffies_minmax, 09/08/99, Carlos H. Bauer.
|
|
* Added proc_doulongvec_minmax, 09/08/99, Carlos H. Bauer.
|
|
* Changed linked lists to use list.h instead of lists.h, 02/24/00, Bill
|
|
* Wendling.
|
|
* The list_for_each() macro wasn't appropriate for the sysctl loop.
|
|
* Removed it and replaced it with older style, 03/23/00, Bill Wendling
