Whoops; sorry about that.

The atomic headers are generated, and this kerneldoc comment is
generated from the template in scripts/atomic/kerneldoc/sub_and_test

You'll need to modify that then run:

sh scripts/atomic/gen-atomics.sh

... to regenerate all the affected instances of ${atomic}_sub_and_test()

Thanks,
Mark.
