A retrigger on B/ibm-gt 4.15.0-1084.93 using lagalla passed. Appears to maybe be a flakey test

This was fixed in stress-ng in commit:

    core-vmstat: use shim wrapper of strlcpy to avoid compat linking issues

https://kernel.ubuntu.com/git/cking/stress-ng.git/commit/?id=4b12a9e7c3d0e1d777c6ff4225913ca33534ccf2

Apologies for breaking the test. This required a libbsd shim compat call to use the safer strlcpy

[Colin Ian King (colin-king)]

Please re-run the test and see if this fixes the issue.

[Po-Hsu Lin (cypressyew)]

A re-run on Trusty / X-fips shows this is now working.
Thank you!
