Ideally, I think we'd have a symlink from the build id, but that's a separate issue. AFAIK, the only thing that actually references these files is Fedora's gdb, which is finding them from Fedora's build-id symlinks, which should work fine regardless of what the thing is called. How's this for a patch description: make vdso_install has been broken since this commit: commit 6f121e548f83674ab4920a4e60afb58d4f61b829 Author: Andy Lutomirski Date: Mon May 5 12:19:34 2014 -0700 x86, vdso: Reimplement vdso.so preparation in build-time C because the names of the files to be installed changed. This fixes vdso_install to install the right files. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
