  "message": "rescounters: add res_counter_uncharge_until()\n\nWhen killing a res_counter which is a child of other counter, we need to\ndo\n\n\tres_counter_uncharge(child, xxx)\n\tres_counter_charge(parent, xxx)\n\nThis is not atomic and wastes CPU.  This patch adds\nres_counter_uncharge_until().  This function\u0027s uncharge propagates to\nancestors until specified res_counter.\n\n\tres_counter_uncharge_until(child, parent, xxx)\n\nNow the operation is atomic and efficient.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@redhat.com\u003e\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nCc: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Ying Han \u003cyinghan@google.com\u003e\nCc: Glauber Costa \u003cglommer@parallels.com\u003e\nReviewed-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
