I'm seeing a new intermittent xfstests failure with v4.4-rc3 using XFS and DAX. The test that is failing is generic/083, and it fails about 50% of the time in my setup. Here's the output: FSTYP -- xfs (debug) PLATFORM -- Linux/x86_64 lorwyn 4.4.0-rc3 MKFS_OPTIONS -- -f -bsize=4096 /dev/pmem0p2 MOUNT_OPTIONS -- -o dax -o context=system_u:object_r:nfs_t:s0 /dev/pmem0p2 /mnt/xfstests_scratch generic/083 2s ... 2s _check_xfs_filesystem: filesystem on /dev/pmem0p2 is inconsistent (r) (see /root/xfstests/results//generic/083.full) Ran: generic/083 Failures: generic/083 Failed 1 of 1 tests The 083.full file is pretty short, and can be found at the end of this email. My test setup is a pair of 4GiB PMEM partitions in a KVM virtual machine. This test passes 100% of the time with v4.3 using DAX, and it passes 100% of the time in my setup with DAX disabled using v4.4-rc3. Please let me know if you have any other questions about how to reproduce the failure. I'm also happy to test patches.
