Comment 9 for bug 1847340

Test results with stress-ng.

The original kernels hit the issue (very often on Bionic, less often on Focal.)
The modified kernels don't (in 2x the number of runs on both Bionic and Focal.)

Number of tests (stress-ng + crash + mount) that mount PASSED or FAILED (ie, problem was hit.)
