// generic/042 and generic/392 are failing because ext4 forces the
// resolution of all delayed allocation writes before allowing the
// punch operation to proceed.  We probably want to see if we can avoid
// this for the future, but what ext4 is doing is legal, so just skip
// the test for now
generic/042
generic/392

// generic/04[456] tests how truncate and delayed allocation works
// ext4 uses the data=ordered to avoid exposing stale data, and
// so it uses a different mechanism than xfs.  So these tests will fail
generic/044
generic/045
generic/046

// generic/223 tests file alignment, which works on ext4 only by
// accident because we're not RAID stripe aware yet, and works at all
// because we have bias towards aligning on power-of-two block numbers.
// It is a flaky test for some configurations, so skip it.
generic/223

// The shutdown ioctl will sometimes result in a corrupted file systems
// it really shouldn't, but we probably won't have it fixed for a while.
// So exclude it for now.
