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.
