Regressions (compared to build v4.4.96)

dell-poweredge-r200 - x86_64: ltp-syscalls-tests:

• readahead02

Please ignore this LTP readahead02 failure. Re-tested and it got pass.

• cd /opt/ltp/testcases/bin/
• export TMPDIR=/home
• ./readahead02

Just because it passed once, or failed once doesn’t imply that there isn’t an issue. It just starts to suggest something is potentially intermittent. 2 runs isn’t much of a data point.

I agree that this "readahead02" test case is intermittent failure we have seen three months ago (Aug. 17, 2017). Please refer this link, https://qa-reports.linaro.org/lkft/linux-stable-4.4-oe/tests/ltp-syscalls-te...
