[PATCH v3 0/9] hacking: make 'kernel hacking' menu better structurized

[Changbin Du]

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 structurized yet.

Early discussion is here:

v3:
  o change subject prefix.
v2:
  o rebase to linux-next.
  o move DEBUG_FS to 'Generic Kernel Debugging Instruments'
  o move DEBUG_NOTIFIERS to 'Debug kernel data structures'

Changbin Du (9):
  hacking: Group sysrq/kgdb/ubsan into 'Generic Kernel Debugging
    Instruments'
  hacking: Create submenu for arch special debugging options
  hacking: Group kernel data structures debugging together
  hacking: Move kernel testing and coverage options to same submenu
  hacking: Move Oops into 'Lockups and Hangs'
  hacking: Move SCHED_STACK_END_CHECK after DEBUG_STACK_USAGE
  hacking: Create a submenu for scheduler debugging options
  hacking: Move DEBUG_BUGVERBOSE to 'printk and dmesg options'
  hacking: Move DEBUG_FS to 'Generic Kernel Debugging Instruments'
