  "message": "ring-buffer: Add per_cpu ring buffer control files\n\nAdd a debugfs entry under per_cpu/ folder for each cpu called\nbuffer_size_kb to control the ring buffer size for each CPU\nindependently.\n\nIf the global file buffer_size_kb is used to set size, the individual\nring buffers will be adjusted to the given size. The buffer_size_kb will\nreport the common size to maintain backward compatibility.\n\nIf the buffer_size_kb file under the per_cpu/ directory is used to\nchange buffer size for a specific CPU, only the size of the respective\nring buffer is updated. When tracing/buffer_size_kb is read, it reports\n\u0027X\u0027 to indicate that sizes of per_cpu ring buffers are not equivalent.\n\nLink: http://lkml.kernel.org/r/1328212844-11889-1-git-send-email-vnagarnaik@google.com\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Michael Rubin \u003cmrubin@google.com\u003e\nCc: David Sharp \u003cdhsharp@google.com\u003e\nCc: Justin Teravest \u003cteravest@google.com\u003e\nSigned-off-by: Vaibhav Nagarnaik \u003cvnagarnaik@google.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
