You mean block device should not return -EIO anyway if
it doesn't want XFS to suddenly shut down?
As Mikulas said, connection failure often be the cause of
I/O error from the underlying devices.
That ext4 and XFS are both determine shutting down in
erroneous journal writes is also due to the limitation of journal write?
or just a compromise in implementation? This is just for my curiosity.

Strange.
These daemons should stop in few seconds on the current configuration.
Yes, partial in a sense. Not all the daemons stop immediately but
for the client the logical device is seen as being blocked up
returning -EIO on every I/O. I don't think this behavior harms the
upper layer.
Currently, sync_proc is like this.
It sleeps for few seconds, wakes up and
meets wait_on_blockup() to dump that message and halts itself.
recorder_proc is implemented in the same way.
int sync_proc(void *data)
{
int r;
struct wb_cache *cache = data;
struct wb_device *wb = cache->wb;
unsigned long intvl;
while (!kthread_should_stop()) {
wait_on_blockup();
/* sec -> ms */
intvl = ACCESS_ONCE(cache->sync_interval) * 1000;
if (!intvl) {
schedule_timeout_interruptible(msecs_to_jiffies(1000));
continue;
}
flush_current_buffer(cache);
RETRY(blkdev_issue_flush(cache->device->bdev, GFP_NOIO, NULL));
schedule_timeout_interruptible(msecs_to_jiffies(intvl));
}
return 0;
}
XFS shuts down, go crazy and it disturbs the kthread to wake up?

I turned the level up to 7. Here is the one.
