This rpm spec file is based off Fedora's libblkio 1.2.2 spec file.
CentOS Stream requires vendored crate dependencies, so it was necessary
modify the spec file to use that approach instead of declaring build
dependencies.
The libblkio-vendor-v1.2.2.tar.bz2 file was generated by running cargo
vendor in the libblkio-v1.2.2 source tree and packaging up the vendor/
directory and .cargo/config.toml.
