Bug description:
[Impact]
hisi_qm does not clean up kernel process after calculation is done. Many
zombie processes slow down system. After checkbox cpu stress test, it takes
more then 2min to ssh in.
[Test Plan]
1) stress-ng --aggressive --verify --timeout 300 --metrics-brief --tz --times
--af-alg 0
2) ps aux | grep hisi_qm | wc -l
Expected result is less then 100
[Regression Risk]
hisi_qm only affects kunpeng920 platform. Minimal risk for other platform,
and full regression test is needed on kunpeng920.
=======================
[Bug Description]
With focal 5.4 kernel, crypto driver does not clean up its created process
when calculation is done. Many zombie processes slow down system. e.g. Takes
more then 10sec for ssh connection.
[Steps to Reproduce]
1) Install Ubuntu 20.04 with GA (5.4) kernel
2) sudo apt install -y stress-ng
3) stress-ng --aggressive --verify --timeout 300 --metrics-brief --tz --times
--af-alg 0
4) ps aux | grep hisi_qm | wc -l
[Actual Results]
>100000
[Expected Results]
<100
[Reproducibility]
100%
[Additional information]
Can not reproduce with focal HWE (5.8) kernel.
