liburing-devel corresponding to the liburing version in appstream is 
available in EPEL. However, EPEL is not enabled for 
storage9s-gluster-11-el9s.

Not directly related, but assuming you use liburing by utilizing EPEL 
and at the same time also drop other dependencies from 
storage9s-gluster-11-el9s which are satisfied by EPEL, the resulting 
glusterfs rpms might actually end up being the very similar to what we 
currently provide for EL, i.e., in storage9-gluster-11-el9. The 
glusterfs packages provided for EL do not suffers from these liburing 
conflicts. Obviously these are build using RHEL build roots, but very 
likely will work on Stream as well.
