| Thread-topic: | question about shadow_blow_tables |
I remembered that some portion of shadow table is per-domain property, which is why a domain shadow lock is used. Then at shadow_blow_tables, should target domain be paused before blowing all tables in case some entries are still in use in guest context on other cpus for a SMP guest. Or some delay unhook mechanism is used to check above condition?
