liburing.so.1(LIBURING_0.1)(64bit) - needed by qemu
liburing.so.2(LIBURING_2.0)(64bit) - needed by glusterfs

I guess liburing was not available in earlier versions, and was
therefore added to the gluster repository. We'll have to remove the
gluster version and rebuild the package against the liburing version
that is now part of CentOS Stream 9.

The gluster repository seems to have a newer liburing version, which
makes it difficult to downgrade to the appstream version for users that
have the glusterfs-server package installed. Users in this situation
may need to add --allowerasing while updating to the a rebuild of the
glusterfs package.

Does anyone have an idea on how this can be handled best?

Thanks,
Niels
