Subject: Fix: enable event loglevel match function
X-Git-Tag: v2.0.3~1
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=4cec12324076987269d5de511084a75d9733b6b4;p=lttng-tools.git

Fix: enable event loglevel match function

For the loglevel type ALL, the value set in an event inside the session
daemon is -1 where the value received from the client is 0. For this
loglevel type, the loglevel does not matter.

This fixes the commit c0657016bbb98e1769edbaba8c00221f964c7402 done
before version 2.0.2.

(Closes #283 #287)
