    It looks like it's the writeback patches, from a quick glance. Did it
    get stuck, or did it still make progress? Thanks for testing, please let
    me know if it triggers with just wb-v8. Can you send me your .config,
    too? I'm assuming no special ext4 mount options, right? I used ext4 as
    well for testing, using -o barrier=0 for most of the runs.

    Irregardless, I'll try this test and poke a bit at it and find out what
    the issue is.
