Updated trace-cmd packages that add one enhancement are now available for Red Hat Enterprise Linux 6.
The trace-cmd packages contain a command line tool that interfaces with ftrace in the kernel.
This update adds support for the "-i" option that can be used to ignore events. By default, if an event is listed but cannot be found by the trace-cmd utility on the system, the utility exits. This option allows trace-cmd execution to continue even when an event is listed on the command line but cannot be found on the system.
All users of trace-cmd are advised to upgrade to these updated packages, which add this enhancement.
