  "message": "ftrace: Allow stealing pages from pipe buffer\n\nUse generic steal operation on pipe buffer to allow stealing\nring buffer\u0027s read page from pipe buffer.\n\nNote that this could reduce the performance of splice on the\nsplice_write side operation without affinity setting.\nSince the ring buffer\u0027s read pages are allocated on the\ntracing-node, but the splice user does not always execute\nsplice write side operation on the same node. In this case,\nthe page will be accessed from the another node.\nThus, it is strongly recommended to assign the splicing\nthread to corresponding node.\n\nSigned-off-by: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n",
