The documentation produced by lttng enable-channel -h should not mention -j
When an error is found in the command line (or -h is used) for lttng enable-channel, one sees among other lines, the following 2 lines:
--buffers-uid Use per UID buffer (-u/-j only) --buffers-pid Use per PID buffer (-u/-j only)
However, -j is not mentioned anywhere else. Further, on the mailing list there have been other comments about other limitations of JUL that need to be documented.
