So. I'd suggestd these 2 simple patches for now.
Please note that 2/2 is really trivial, it only adds EXPORT_SYMBOL but
avoids the possible cleanups to minimize the conflicts with the pending
cmwq changes. However, please feel free to ignore this patch.
As for 1/2, imho it is always better to fix the bug asap, even if it is
minor.
Oleg.
