Subject: Fix: worker structure is leaked in run_as process
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=340cf6726ea8249d9c054fbbe03e8c09a0fd6e73;ds=sidebyside

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.
