Hello Jens,

I would appreciate it if other names would be chosen than BLK_STS_RESOURCE
and BLK_STS_DEV_RESOURCE, e.g. names that directly refer to the fact that
one of the two status codes causes the queue to be rerun and the other not.
I'm afraid that the currently chosen names will cause confusion.

Thanks,

Bart.
