  "message": "vmscan: rename sc.may_swap to may_unmap\n\nsc.may_swap does not only influence reclaiming of anon pages but pages\nmapped into pagetables in general, which also includes mapped file pages.\n\nIn shrink_page_list():\n\n\t\tif (!sc-\u003emay_swap \u0026\u0026 page_mapped(page))\n\t\t\tgoto keep_locked;\n\nFor anon pages, this makes sense as they are always mapped and reclaiming\nthem always requires swapping.\n\nBut mapped file pages are skipped here as well and it has nothing to do\nwith swapping.\n\nThe real effect of the knob is whether mapped pages are unmapped and\nreclaimed or not.  Rename it to `may_unmap\u0027 to have its name match its\nactual meaning more precisely.\n\nSigned-off-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: MinChan Kim \u003cminchan.kim@gmail.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
