Already covered by smb_mb conversion patch.
Will credit you in v2, but these patches are not exactly
interchangeable. In fact, I was hoping to make your work of removing
dependence on deprecated symbols easier here, since there there seem to
be multiple diverging opinions about the scope and the best way forward.
If you want, can just make that into one patch which does
the conversion to bool and gets rid of smp_mb.
Not sure how they are related, especially since this one seems to be
trivial and safe, while the bool one is potentially tricky.
