  "message": "mm: add swap cache interface for swap reference\n\nIn a following patch, the usage of swap cache is recorded into swap_map.\nThis patch is for necessary interface changes to do that.\n\n2 interfaces:\n\n  - swapcache_prepare()\n  - swapcache_free()\n\nare added for allocating/freeing refcnt from swap-cache to existing swap\nentries.  But implementation itself is not changed under this patch.  At\nadding swapcache_free(), memcg\u0027s hook code is moved under\nswapcache_free().  This is better than using scattered hooks.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nReviewed-by: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nAcked-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nCc: YAMAMOTO Takashi \u003cyamamoto@valinux.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
