      "message": "tracing, page-allocator: add a postprocessing script for page-allocator-related ftrace events\n\nThis patch adds a simple post-processing script for the\npage-allocator-related trace events.  It can be used to give an indication\nof who the most allocator-intensive processes are and how often the zone\nlock was taken during the tracing period.

While there is a\nbinary format, the expectation is that the binary output can be readily\ntranslated into text and post-processed offline.  Obviously if the text\nformat changes, the parser will break but the regular expression parser is\nfairly rudimentary so should be readily adjustable.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Larry Woodman \u003clwoodman@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Li Ming Chun \u003cmacli@brc.ubc.ca\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
