   - why are you using rw_obj_alloc() since you always need it, and
     you could just define the locks as structs not pointers and call
     rw_init() on them?

The historical reason to use rw_obj_alloc was to get a cache line
alignment.  But we can do that with static variables now using the
__cacheline_aligned attribute:

static krwlock_t        xyz_lock __cacheline_aligned;
