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
