My original patch (https://lkml.org/lkml/2018/4/4/447) to fix this isse
probably won't work. This is my second attempt to fix it.
I don't have the setup to reproduce the problem. Could someone try it to see
if it can eliminate the warning?

locking/rwsem: Add a new RWSEM_WRITER_OWNED_NOSPIN flag
locking/percpu-rwsem: Mark rwsem as non-spinnable in
percpu_rwsem_release()
