There's been a long standing issue where only +one version of a debuginfo info package can be installed at a time. There's +been an effort for Fedora for parallel debuginfo to rectify this problem. + +Part of the requirement to allow parallel debuginfo to work is that build ids +are unique between builds. The existing upstream rpm implementation ensures +this by re-calculating the build-id using the version and release as a +seed. This doesn't work 100% for the kernel because of the vDSO which is +its own binary and doesn't get updated when embedded. + +Fix this by adding some data in an ELF note for both the kernel and modules. +The data is controlled via a Kconfig option so distributions can set it +to an appropriate value to ensure uniqueness between builds. + +Suggested-by: Masahiro Yamada <yamada.masahiro@socionext.com> +Signed-off-by: Laura Abbott <labbott@redhat.com> +--- +v6: Added more detail to the commit text about why exactly this feature +is useful.
