| Subject: [PATCH 41/48] tracing: Make tracing_set_clock() non-static |
| |
| Allow tracing code outside of trace.c to access tracing_set_clock(). |
| |
| Some applications may require a particular clock in order to function |
| properly, such as latency calculations. |
| |
| Also, add an accessor returning the current clock string. |
