This option may have a slight performance impact because a 12 portion of the kernel code won't be covered by a TLB anymore. 13 If in doubt, say "N". 14 15endmenu 16 17config DEBUG_STACKOVERFLOW 18 bool "Check for stack overflows" 19 default y 20 depends on DEBUG_KERNEL 21 ---help--- 22 Say Y here if you want to check the overflows of kernel, IRQ 23 and exception stacks. This option will cause messages of the 24 stacks in detail when free stack space drops below a certain 25 limit. 26 If in doubt, say "N". 27
