This series add a helper to the tracing framework to trace arrays. Patch 1 add the helper and patches 2 and 3 update the traceevent library to parse them. They've been tested with trace-cmd.
Changes since v4[0]: - Specify the element size in __print_array() as bytes instead of bits
Changes since v3: - use %zu to print size_t
Changes since v2: - Changed BUG() into a trace_seq_printf() - Add BUILD_BUG_ON() to chase mistakes in element sizes on build - Add patch 2 to avoid repeating code in patch 3. - print a warning in traeevent if the size of the array is not valid
