Subject: Fix: PERROR spam when `tracing` group does not exist
X-Git-Tag: v2.11.6~9
X-Git-Url: https://git.lttng.org/?a=commitdiff_plain;ds=sidebyside;h=aa1f1a266341650a084a96f05ebe8e2a5da2f801;p=lttng-tools.git

Fix: PERROR spam when `tracing` group does not exist

The session daemon prints a PERROR on launch when the tracing group does
not exist. This should not occur when the group simply does not exist as
this is not an error. In that case (ESRCH), a DBG statement is
sufficient.
