sorry for introducing that error, but I'm a bit confused by the
workqueue documentation.
My assumption was, that deleting hwsim radios is reclaiming memory, and
since this queue does nothing else it would save/necessary to set this flag.

Maybe a hint in the documentation, that a work item on a WQ_MEM_RECLAIM
queue must not call flush of an !WQ_MEM_RECLAIM queue would be nice.
Maybe it's kind of obvious, but there is also a reminder not to forget
that flag, if a queue may have work items that reclaim memory

Yeah, honestly, I'm not really sure either. Clearly we can't set it,
but other drivers also set it...

I don't think it was *intended* for when you're freeing memory, since I
think reclaiming is what happens when you write out dirty buffers to
disk etc.
