  "message": "ksm: separate stable_node\n\nThough we still do well to keep rmap_items in the unstable tree without a\nseparate tree_item at the node, for several reasons it becomes awkward to\nkeep rmap_items in the stable tree without a separate stable_node: lack of\nspace in the nicely-sized rmap_item, the need for an anchor as rmap_items\nare removed, the need for a node even when temporarily no rmap_items are\nattached to it.\n\nSo declare struct stable_node (rb_node to place it in the tree and\nhlist_head for the rmap_items hanging off it), and convert stable tree\nhandling to use it: without yet taking advantage of it.  Note how one\nstable_tree_insert() of a node now has _two_ stable_tree_append()s of the\ntwo rmap_items being merged.\n\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Izik Eidus \u003cieidus@redhat.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
