$ grep 083  tests/xfs/group

Yup, it's expected to fail, and given that it's "dangerous" likely
to hang the filesystem or crash the kernel.

Tests that are expected to pass and act as regression tests are in
the auto group. If a test is not in the auto group, it's usually
because the test is either broken or will not complete due
hanging/crashing. i.e use:

# MOUNT_OPTIONS="-o dax" ./check -g auto

For regression testing.

Cheers,

Dave.
