19 * The run-as process is launched by forking without an exec*() call. This means
20 * that any resource allocated before the run-as worker is launched should be
21 * cleaned-up after the fork(). This callback allows the user to perform this
22 * clean-up.
23 *
24 * Note that the callback will _not_ be invoked if the LTTNG_DEBUG_NOCLONE
25 * environment variable is set as the clean-up is not needed (and may not be
26 * expected).
27 *
28 * A negative return value will cause the run-as process to exit with a non-zero
29 * value.
