Subject: [PATCH] rt-tests: cyclictest.8: Remove invalid tracing options from
|
||
|
|
the manpage
|
||
|
|
|
||
|
|
Most tracing options have been removed from cyclictest since the
|
||
|
|
user can now use trace-cmd together with cyclictest to get the same
|
||
|
|
functionality. Update the manpage to reflect this.
