From fc2f5f10f9bc5e58d38e9fda7dae107ac04a799f Mon Sep 17 00:00:00 2001 From: Jens Remus Date: Mon, 29 Apr 2024 17:02:53 +0200 Subject: s390/vdso: Create .build-id links for unstripped vdso files Citing Andy Lutomirski from commit dda1e95cee38 ("x86/vdso: Create .build-id links for unstripped vdso files"): "With this change, doing 'make vdso_install' and telling gdb: set debug-file-directory /lib/modules/KVER/vdso will enable vdso debugging with symbols. This is useful for testing, but kernel RPM builds will probably want to manually delete these symlinks or otherwise do something sensible when they strip the vdso/*.so files."
