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