A\nyear ago I was hesitant to engage page_mapcount, now it seems the right fix.\n\nSo remove the page_count hack from try_to_unmap_one; and use activate_page in\nunuse_mm when dropping lock, to replace its secondary effect of helping\nswapoff to make progress in that case.\n\nSimplify can_share_swap_page (now called only on anonymous pages) to check\npage_mapcount + page_swapcount \u003d\u003d 1: still needs the page lock to stabilize\ntheir (pessimistic) sum, but does not need swapper_space.tree_lock for that.\n\nIn do_swap_page, move swap_free and unlock_page below page_add_anon_rmap, to\nkeep sum on the high side, and correct when can_share_swap_page called.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
