kabi一致的话，可以保证insmod ko在不同的kernel 版本之间，因此kabi一致性对用户很重要，可以参考下面的tool来check 两个版本之间的kernel abi是否一致https://github.com/skozina/kabi-dw从下面这段spec文件中可以看出是如何check abi的%if %{with_kabichk}    # create the kABI metadata for use in packaging    # NOTENOTE: the name symvers is used by the rpm backend    # NOTENOTE: to discover and run the /usr/lib/rpm/fileattrs/kabi.attr    # NOTENOTE: script which dynamically adds exported kernel symbol    # NOTENOTE: checksums to the rpm metadata provides list.    # NOTENOTE: if you change the symvers name, update the backend too    echo "**** GENERATING kernel ABI metadata ****"    gzip -c9 < Module.symvers > $RPM_BUILD_ROOT/boot/symvers-$KernelVer.gz    echo "**** kABI checking is enabled in kernel SPEC file. ****"    chmod 0755 $RPM_SOURCE_DIR/check-kabi    if [ -e $RPM_SOURCE_DIR/Module.kabi_%{_target_cpu}$Flavour ]; then        cp $RPM_SOURCE_DIR/Module.kabi_%{_target_cpu}$Flavour $RPM_BUILD_ROOT/Module.kabi        $RPM_SOURCE_DIR/check-kabi -k $RPM_BUILD_ROOT/Module.kabi -s Module.symvers || exit 1        rm $RPM_BUILD_ROOT/Module.kabi # for now, don't keep it around.    else        echo "**** NOTE: Cannot find reference Module.kabi file. ****"    fi%endif %{with_kabichk}
