We could emit a non-aligned end-of-text symbol (we might have it already), and have a script or small .c program in scripts/ or tools/ that looks at vmlinux and displays a user-friendly and accurate list of text and data sizes in the kernel?
And since objtool is technically an 'object files tool', and it already looks at sections & symbols, it could also grow a:
objtool size <objfile>
command that does the sane thing ... I'd definitely start using that, instead of 'size'.
/me runs :-)
Thanks,
Ingo
