Subject: [PATCH 1/2] [RFC] debugobjects: avoid gcc-16.0.1 section mismatch

From: Arnd Bergmann <[email-masked]>

gcc-16 has gained some more advanced inlining techniques that enable
it to inline the is_static_object() function pointer into a specialized
version of lookup_object_or_alloc:

WARNING: modpost: vmlinux: section mismatch in reference: lookup_object_or_alloc.part.0+0x1ac (section: .text) -> is_static_object (section: .init.text)

>From what I can tell, the transformation is correct, as this
is only called when lookup_object_or_alloc() is called from
debug_objects_selftest(), which is also __init.

I have not come up with a good workaround, so this simply marks
is_static_object() as not __init. Since there are currently only two
files where this happens, that may be an easy way out.

If anyone has a better idea for how to deal with that, let me know!
