  12         help
  13           Kprobes allows you to trap at almost any kernel address and
  14           execute a callback function.  register_kprobe() establishes
  15           a probepoint and specifies the callback.  Kprobes is useful
  16           for kernel debugging, non-intrusive instrumentation and testing.
  17           If in doubt, say "N".

  23           Enables the display of the minimum amount of free stack which each
  24           task has ever had available in the sysrq-T and sysrq-P debug output.

  33           intending to debug the kernel, say N here.

  51         bool "Use separate kernel stacks when processing interrupts"
  52         help
  53           If you say Y here the kernel will use separate kernel stacks
  54           for handling hard and soft interrupts.  This can help avoid
  55           overflowing the process kernel stacks.
