XFS tier1/2 regression/functional/stress test nearly done, no obvious error can
be reproducible. Trying to loop run some failed cases. Some details as below:

[0]
Hit 3 times NFS panic, when test on NFS base on XFS. It's a known issue which
fixed on Linux v5.0-rc7. These test has to ben interrupted.

Hit once shared/010 fails on an aarch64(64k pagesize) machine, but haven't got
chance to reproduce it again:
