Subject: run_filter callback takes const event parameter
X-Git-Tag: v2.13.0-rc1~106
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=9c098f2368d48c28ed02d891ff7f2a9fcc84d5d5;p=lttng-ust.git

run_filter callback takes const event parameter

The event parameter of the run_filter callback should be const, because
it should not be modified, only read.
