Description

lttng-tools src/lib/lttng-ctl/lttng-ctl.c:

lttng_enable_event_with_exclusions()

memcpy(&lsm.u.enable.event, ev, sizeof(lsm.u.enable.event));

copy "ev" (non-packed) into a packed structure.

We should copy each field one by one (create a copy_event_to_event_packed() helper to do so).
