If this option is 13 disabled, you allow userspace access to all memory, including 14 kernel and userspace memory. Accidental memory access is likely 15 to be disastrous. 16 Memory access is required for experts who want to debug the kernel. 17 18 If you are unsure, say Y. 19 20config S390_PTDUMP 21 bool "Export kernel pagetable layout to userspace via debugfs" 22 depends on DEBUG_KERNEL 23 select DEBUG_FS 24 ---help--- 25 Say Y here if you want to show the kernel pagetable layout in a 26 debugfs file. This information is only useful for kernel developers 27 who are working in architecture specific areas of the kernel. 28 It is probably not a good idea to enable this feature in a production 29 kernel. 30 If in doubt, say "N" 31 32config DEBUG_SET_MODULE_RONX 33 def_bool y 34 depends on MODULES 35endmenu 36
