[UML] Question about arch/x86/um/vdso/vdso-syms.lds

[Masahiro Yamada]

Hi Richard,


Please let me ask a question about vdso-syms.lds
under arch/x86/um/vdso/.

This file exists since:

commit f1c2bb8b9964ed31de988910f8b1cfb586d30091
Author: Richard Weinberger <richard@xxxxxx>
Date:   Mon Jul 25 17:12:54 2011 -0700

    um: implement a x86_64 vDSO


So, I think you are the right person
to reach out to.


Originally, vdso-syms.lds was linked to vmlinux,
but it is not since:

commit 827880ec260ba048f95fe646b96a205c394fa0f0
Author: Nicholas Piggin <npiggin@xxxxxxxxx>
Date:   Fri Jun 9 15:24:16 2017 +1000

    x86/um: thin archives build fix



Something may be missing from my thought,
but I wonder what vdso-syms.lds is used for.
