Steven Hartland e05aad2d33 Add TRIM support for L2ARC. ... This adds TRIM support to cache vdevs. When ARC buffers are removed from the L2ARC in arc_hdr_destroy(), arc_release() or l2arc_evict(), the size previously occupied by the buffer gets scheduled for TRIMming. As always, actual TRIMs are only issued to the L2ARC after txg_trim_limit. Reviewed by: pjd (mentor) Approved by: pjd (mentor) Obtained from: 31aae37399 MFC after: 2 weeks		2013-03-21 09:34:41 +00:00
