I understand that changing behaviour of existing checks is not desirable.

The -T option to fsx was inspired by the test we used to hunt a bug at
3.8-rc time where 50 concurrent direct io fsx jobs triggered the bug in
about 10 minutes or it was considered fine.

fsx -q xxxf$x -Z -R -W -r 4096 -w 4096

I'll send this test integrated into xfstests harness.
