The warning is only visible after commit 21c05ca88a54 ("workqueue: Add
warnings and ensure one among WQ_PERCPU or WQ_UNBOUND is present") in
the workqueue tree. If it goes via the btrfs tree, there could be a
period during the merge window where the warning appears if the
workqueue tree is merged before the btrfs tree. Not the biggest deal
since it is a runtime warning but there are already other patches in the
workqueue tree that avoid warnings and David already provided an Ack, so
I don't see a reason to deviate from the proper process here. Up to
Tejun and the btrfs folks though.
