Has some problems applying to linux-next. Under 'Compile-time checks and compiler options', "Debug Filesystem" does not belong here. Maybe move it under 'Generic Kernel Debugging Instruments'. I mostly like it. I might have put 'Debug notifier call chains' under 'Debug kernel data structures', but that's not a big deal. -- ~Randy

[PATCH 0/8] kconfig/hacking: make 'kernel hacking' menu better structured
This series is a trivial improvment for the layout of 'kernel hacking' configuration menu. Now we have many items in it which makes takes a little time to look up them since they are not well structured yet. Early discussion is here: https://lkml.org/lkml/2019/9/1/39 Changbin Du (8): kconfig/hacking: Group sysrq/kgdb/ubsan into 'Generic Kernel Debugging Instruments' kconfig/hacking: Create submenu for arch special debugging options kconfig/hacking: Group kernel data structures debugging together kconfig/hacking: Move kernel testing and coverage options to same submenu kconfig/hacking: Move Oops into 'Lockups and Hangs' kconfig/hacking: Move SCHED_STACK_END_CHECK after DEBUG_STACK_USAGE kconfig/hacking: Create a submenu for scheduler debugging options kconfig/hacking: Move DEBUG_BUGVERBOSE to 'printk and dmesg options' lib/Kconfig.debug | 627 -- 1 file changed, 324 insertions(+), 303 deletions(-) -- 2.20.1
