Generally "Furniture" would not extend up to the ceiling, and so not be blocking the spray pattern, that developed for the room. A converted closet will since there is a lintel over what used to be the door that extends to the ceiling. The secondary issue is if the area was included in the area of protection provided by the sprinklers in the room, formerly the "Adjoining room"? If not some method of protection should be supplied, unless a specific exception can be met.
A single head at the top of the closet/linen cabinet should suffice. If you add 14-15 Gpm to a 3x3 space, that cooling effect will be huge, and while water may not directly contact the burning materials, the normally loose fitting shelves of a cabinet, will allow the water to wet the interior surfaces of the cabinet all the way to the floor. So unless this is a "Suppression mode" system, I would say "containment" was the likely result, if a fire occurred in the cabinet/closet with a single sprinkler head at the top.

Also note that obstructions (shelves) are not an issue in a closet. Also it is A.8.15.8.2 that states that sprinklers are not required within furniture is the old text and it was expanded in 07 (and put within the standard ) at 8.1.1(7). That section also states you can attach the furniture to the structure. It doesn't say you can put it within a closet.
