 	should not be using the slab in this way but we should still handle
 	the case more cleanly.
 
+	* module/spl/spl-kmem.c: Remove kmem_set_warning() interface and
+	replace it with KM_NODEBUG flag which can be specific per allocation.
+
+	* module/splat/splat-kmem.c: Tweaked what the idea of a large object
+	is for the kmem:slab_large regression tests because failures were
+	observed for very large kmem objects in newer kernels.
+
+	* include/sys/rwlock.h, module/splat/splat-rwlock.c: The rwlock
+	implementation was simplified because failures were being observed
+	when using the non-generic implementation.  This change leverages
+	the rwsem_is_locked() function instead of directly consulting the
+	rwsem internals which differ per-arch and per-kernel-version.
