  "message": "page-allocator: reset wmark_min and inactive ratio of zone when hotplug happens\n\nSolve two problems.\n\nWhenever memory hotplug sucessfully happens, zone-\u003epresent_pages\nhave to be changed.\n\n1) Now memory hotplug calls setup_per_zone_wmark_min only when\n   online_pages called, not offline_pages.\n\n   It breaks balance.\n\n2) If zone-\u003epresent_pages is changed, we also have to change\n   zone-\u003einactive_ratio.  That\u0027s because inactive_ratio depends on\n   zone-\u003epresent_pages.\n\nSigned-off-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nAcked-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
