34  * The slab allocator, as described in the following two papers:

800 	DEFAULTMUTEX,				/* start of slab layer */
884 	umem_slab_t	*ump_slab;	/* slab accoring to umem_findslab() */
1052  * Debugging support.  Given a buffer address, find its slab.

1631 	 * If this slab isn't currently on the freelist, put it there.
1651 		 * There are no outstanding allocations from this slab,
1775  * Free each object in magazine mp to cp's slab layer, and free mp itself.
1961 		 * so fall through to the slab layer.
1969 	 * so get a raw buffer from the slab layer and apply its constructor.
