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. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
