| 2 | |
| 3 | tracing_enabled use in the kernel is being deprecated as per commit |
| 4 | 6752ab4a9c30 [tracing: Deprecate tracing_enabled for tracing_on] in |
| 5 | the linux mainline kernel. tracing_enabled use will generate a warning |
| 6 | and may no longer function as expected, therefore move to use tracing_on. |
