Under /proc/sys/kernel there exists a parameters called

Am I mistaken in my analysis?
./kernel/sysctl.c:
.procname = "kstack_depth_to_print",
.data = &kstack_depth_to_print,
Note that this bit is inside an "#if defined(CONFIG_X86)" block meaning that
only the the one(s) below arch/x86 are related:
./arch/x86/kernel/traps_64.c:
int kstack_depth_to_print = 12;
for(i=0; i < kstack_depth_to_print; i++) {
kstack_depth_to_print = simple_strtoul(s,NULL,0);
./arch/x86/kernel/traps_32.c:
int kstack_depth_to_print = 24;
for(i = 0; i < kstack_depth_to_print; i++) {
kstack_depth_to_print = simple_strtoul(s, NULL, 0);
These do use the sysctl set value. Note that this sysctl works by just
directly changing the global variable kstack_depth_to_print. That 12/24 you
see is just an initial value.
