``do_strip``
------------
If ``KERNEL_IMAGE_STRIP_EXTRA_SECTIONS`` is defined, this task strips
If :term:`KERNEL_IMAGE_STRIP_EXTRA_SECTIONS` is defined, this task strips
the sections named in that variable from ``vmlinux``. This stripping is
typically used to remove nonessential sections such as ``.comment``
sections from a size-sensitive configuration.
Common sections to strip:
- ``.comment``: Holds compiler version strings and information
- ``.note.*``: Extra notes often left by the compiler
- ``.debug``: Debugging information
