I have replaced the singlethreaded wq with the call suggested by Tejun:
https://lkml.org/lkml/2011/6/17/99

If this is a problem, I can rework this, and remove the code, which is not
going to be needed, when the system_wq is in use, but I would like to keep the
alloc_workqueue way, since it is going to be easier for us to experiment with
parameters, if we face with issues.
