From 3ae7020543db0b769538e64d1ce8d51fceff60ca Mon Sep 17 00:00:00 2001 From: Ingo Molnar <mingo@elte.hu> Date: Wed, 26 Nov 2008 10:02:00 +0100 Subject: [PATCH] debugobjects: add boot parameter default value Impact: add .config driven boot parameter default value Right now debugobjects can only be activated if the debug_objects boot parameter is passed in via the boot command line. Make this more convenient (and randomizable) by also providing a .config method. Enable it by default. (DEBUG_OBJECTS itself is default-off) Signed-off-by: Ingo Molnar <mingo@elte.hu> --- lib/Kconfig.debug | 8 ++++++++ lib/debugobjects.c | 4 +++- 2 files changed, 11 insertions(+), 1 deletion(-) diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index b0f239e443bc..124ece1e67ad 100644 --- a/lib/Kconfig.debug +++ b/lib/Kconfig.debug @@ -252,6 +252,14 @@ config DEBUG_OBJECTS_TIMERS timer routines to track the life time of timer objects and validate the timer operations. +config DEBUG_OBJECTS_ENABLE_DEFAULT + int "debug_objects bootup default value (0-1)" + range 0 1 + default "1" + depends on DEBUG_OBJECTS + help + Debug objects boot parameter default value + config DEBUG_SLAB bool "Debug slab memory allocations" depends on DEBUG_KERNEL && SLAB diff --git a/lib/debugobjects.c b/lib/debugobjects.c index e3ab374e1334..5d99be1fd988 100644 --- a/lib/debugobjects.c +++ b/lib/debugobjects.c @@ -45,7 +45,9 @@ static struct kmem_cache *obj_cache; static int debug_objects_maxchain __read_mostly; static int debug_objects_fixups __read_mostly; static int debug_objects_warnings __read_mostly; -static int debug_objects_enabled __read_mostly; +static int debug_objects_enabled __read_mostly + = CONFIG_DEBUG_OBJECTS_ENABLE_DEFAULT; + static struct debug_obj_descr *descr_test __read_mostly; static int __init enable_object_debug(char *str)
