Saso Kiselkov 3bec585e6c Illumos 4897 - Space accounting mismatch in L2ARC/zpool 
4897 Space accounting mismatch in L2ARC/zpool

Reviewed by: Matthew Ahrens <mahrens@delphix.com>
Reviewed by: Boris Protopopov <bprotopopov@hotmail.com>
Approved by: Dan McDonald <danmcd@omniti.com>

From the illumos issue tracker:

	L2ARC vdev space usage statistics are calculated as the delta
	between the maximum and minimum vdev offset ever written to
	by the L2ARC fill thread, but do not inform the user of how
	much space in between these two offsets is actually taken up by
	cached buffers. This fix changes that so that vdev space usage
	stats on L2ARC devices accurately track the volume of buffers
	stored on them, allowing users to see the exact L2ARC usage in
	"zpool iostat -v".
