MDEV-24114 : Crash: WSREP: invalid state ROLLED_BACK (FATAL)10.2-MDEV-25114
Reverts fix for MDEV-23328 i.e. commit 29bbcac0ee841
In this fix we try to modify normal SQL KILL in a following way:
trx_id= thd_to_trx(victim_thd)->id;
mutex_unlock(victim_thd->LOCK_thd_data);
mutex_unlock(victim_thd->LOCK_thd_kill);
lock_mutex_enter
trx=find_and_lock_trx_by_id(trx_id)
mytex_lock(trx->mysql_thd->LOCK_thd_kill);
mutex_lock(trx->mysql_thd->LOCK_thd_data)
For THD::awake() we use:
mutex_lock(thd->LOCK_thd_kill);
mutex_lock(thd->LOCK_thd_data);
thd->awake();
mutex_unlock(thd->LOCK_thd_data);
mutex_unlock(thd->LOCK_thd_kill);
For THD::set_killed in most cases we use
mutex_lock(thd->LOCK_thd_kill);
mutex_lock(thd->LOCK_thd_data);
thd->set_killed_no_mutex(...);
mutex_unlock(thd->LOCK_thd_data);
mutex_unlock(thd->LOCK_thd_kill);
