  "message": "ring_buffer: compressed event header\n\nRB_MAX_SMALL_DATA \u003d 28bytes is too small for most tracers, it wastes\nan \u0027u32\u0027 to save the actually length for events which data size \u003e 28.\n\nThis fix uses compressed event header and enlarges RB_MAX_SMALL_DATA.\n\n[ Impact: saves about 0%-12.5%(depends on tracer) memory in ring_buffer ]\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nLKML-Reference: \u003c49F13189.3090000@cn.fujitsu.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
