Subject: Fix: worker structure is leaked in run_as process
X-Git-Tag: v2.9.11~1
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=acb3ccb97067a032b86ea8a0083057a04b687961;p=lttng-tools.git

Fix: worker structure is leaked in run_as process

The run_as structure (handle) is allocated and initialized before
the fork() that spawns the run_as process. Currently, that structure
is only cleaned-up on the parent's end.

This fix performs the clean-up on the worker's side as well.
