commit f9c9104288da543cd64f186f9e2fba389f415630 upstream.
In the cae of the REQ_OP_ZONE_RESET_ALL operation, the command sector is ignored and the operation is applied to all sequential zones. For these commands, tracing the effect of the command using the command sector to determine the target zone is thus incorrect.
Fix null_zone_mgmt() zone condition tracing in the case of REQ_OP_ZONE_RESET_ALL to apply tracing to all sequential zones that are not already empty.
