[Qemu-devel] [PATCH 3/3] Samples to add a tracepoint.

[Prerna Saxena]

Steps for adding a tracepoint :
1. In trace-entries.h, add a DECLARE_TRACE() in the said format.
2. In trace-entries.c:
    i) add a DEFINE_TRACE() for the tracepoint in the said format.
    ii) add an INIT_TRACE(name) for the tracepoint in the function 
init_tracepoints(void)
3. The call site should have a 'trace_name(args..)'
(Remember to include "trace-entries.h" in the file where the tracepoint 
is logged)

This patch adds tracepoints to virtio_blk_rw_complete() and paio_submit()
