I didn´t yet provide such a test case.
At the moment I can only reproduce this kworker thread using a CPU for
minutes case with my /home filesystem.
A mininmal test case for me would be to be able to reproduce it with a
fresh BTRFS filesystem. But yet with my testcase with the fresh BTRFS I
get 4800 instead of 270 IOPS.
