  "message": "[PATCH] fix can_share_swap_page() when !CONFIG_SWAP\n\ncan_share_swap_page() is used to check if the page has the last reference.\nThis avoids allocating a new page for COW if it\u0027s the last page.\n\nHowever, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0,\nthus always causes a copy for the last COW page.  The below simple patch\nfixes it.\n\nSigned-off-by: Hua Zhong \u003chzhong@gmail.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: 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",
