Hi experts

I reproduced this issue during stress test on reset_controller, could you help check it, thanks.

Reproduce steps on initiator side:
num=0
while [ 1 ]
do
	echo "-------------------------------$num"
	echo 1 >/sys/block/nvme0n1/device/reset_controller || exit 1
	((num++))
done

Here is the full log:

I'm using CX5-LX device and have not seen any issues with it.

Would it be possible to retest with kmemleak?
