  "message": "[PATCH] zoned vm counters: convert nr_mapped to per zone counter\n\nnr_mapped is important because it allows a determination of how many pages of\na zone are not mapped, which would allow a more efficient means of determining\nwhen we need to reclaim memory in a zone.\n\nWe take the nr_mapped field out of the page state structure and define a new\nper zone counter named NR_FILE_MAPPED (the anonymous pages will be split off\nfrom NR_MAPPED in the next patch).\n\nWe replace the use of nr_mapped in various kernel locations.  This avoids the\nlooping over all processors in try_to_free_pages(), writeback, reclaim (swap +\nzone reclaim).\n\n[akpm@osdl.org: bugfix]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
