v3: Remove one duplicated missing device output Use the advice from Anand Jain, not to add new members in btrfs_device, but use a new structure extra_rw_degrade_errors, to record error when sending down/waiting device.
Suggested local variables because, v2 had theoretical bug as assessed before. The actual fix (while the variables continue to be at struct device) may not be in the scope of this patch, as the btrfs as such would not handle the intermittent device disappear/reappear as of now. So though I believe in the long term the barrier failure should be part of per device dev_stat rather, but at the moment to keep the original design as it is in the scope of this patch a local stack variable will suffice.
Hope this clarifies better. Thanks, Anand -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
