# Versioning must be the same when building both inside nvidia and kernel pkg,
# but the first part will indicate a newer build, the second part will indicate from which SRPM
# this module was built from and will allow to avoid same filenames of RPMs with
# modules from different SRPMs even if they are built at the same time (second).
# Unfortunately, if we generate release inside %%kroko_kmod_pkg, every usage of
# a macro with it will cause its regeneration, so it may be incosistent across one package.
# Usage example:
# %%define kroko_release %%kroko_mk_release -n %%{NAME}
# %%kroko_kmod_pkg -r %%kroko_mk_release <...>
