[Qemu-devel] [PATCH 0/2] improve tracing

Current trace system have a drawback: parameters of trace functions
are calculated even if corresponding tracepoint is disabled. Also, it
looks like trace function are not actually inlined by compiler (at
least for me).

Here is a fix proposal: move from function call to macros. Patch 02
is an example, of how to reduce extra calculations with help of
patch 01.

Vladimir Sementsov-Ogievskiy (2):
  trace: do not calculate arguments for disabled trace-points
  monitor: improve tracing in handle_qmp_command
