Could consider luns_avail instead mutex?
That would be wrong. I think it is essential that scan_mutex is used in
this patch. Additionally, the lock inversion is between devfreq->lock
and (c->notifiers)->rwsem so it seems unlikely to me that Ziqi's patch
is the patch that introduced the reported lock inversion.
