+Subject: [PATCH] Fix bgsaveerr issue in psync wrong offset test (#11043)
+
+The kill above is sometimes successful and sometimes already too late.
+The PING in pysnc wrong offset test got rejected by bgsaveerr because
+lastbgsave_status is C_ERR.
+
+In theory, using diskless can avoid PING being affected, because when
+the replica is dropped, we will kill the child with SIGUSR1, and this
+will not affect lastbgsave_status.
+
+Anyway, this kill is not particularly needed here, dropping the kill
+is the best one, since we do have the waitForBgsave, so just let it
+take care of the bgsave. No need for fast termination.
