--- Comment #1 from jiademing.dd <iesool at 126.com> ---
After analysis, rpc_clnt_notify() will call quota_enforcer_notify(),because
rpc_clnt_register_notify (rpc, quota_enforcer_notify, this) in quota.
glusterfsd exit will call glusterfs_graph_destroy(),in
glusterfs_graph_destroy() will         dlclose (xl->dlhandle).

so if dlclose(xl->dlhandle) before rpc_clnt_notify(),quota.so's
quota_enforcer_notify() invalid, then lead to crash.
