| H A D | nbd.c | e8b35bf5 Thu Jun 10 05:07:37 CDT 2021 Roman Kagan <rvkagan@yandex-team.ru> block/nbd: ensure ->connection_thread is always valid
Simplify lifetime management of BDRVNBDState->connect_thread by
delaying the possible cleanup of it until the BDRVNBDState itself goes
away.
This also reverts
0267101af6 "block/nbd: fix possible use after free of s->connect_thread"
as now s->connect_thread can't be cleared until the very end.
