Hi Jens, the first patch in this series fixes an error in the decrementing of the counter of the number of groups with pending I/O. This wrong decrement caused loss of throughput or, less likely, of control on I/O. The second patch is a fix of some wrong comments, which somehow contributed to making the above bug more difficult to find.
