I think it is useful to get debugging information as described in the
following texts:

lib/Kconfig.debug
config FRAME_POINTER
         bool "Compile the kernel with frame pointers"
         ...
         default y if (DEBUG_INFO && UML) || ARCH_WANT_FRAME_POINTERS
         help
           If you say Y here the resulting kernel image will be slightly
           larger and slower, but it gives very useful debugging information
           in case of kernel bugs. (precise oopses/stacktraces/warnings)

Documentation/dev-tools/kgdb.rst
This option inserts code to into the compiled executable which saves

   So to or into? :-)

Hi Sergei,

Thanks for pointing that out,this may be a typo which should be "into".

   Oops, I didn't realize it was a quote from the KGDB docs... :-)

I will update the commit message to correct it.

   Thank you!

Thanks,
Tiezhu
