docs:
* mnt_context_get_status:
* @cxt: mount context
*
* Global libmount status.
*
* The real exit code of the mount.type helper has to be tested

* only inform that exec() has been successful.

See sys-utils/mount.c: mk_exit_code()
if (mnt_context_helper_executed(cxt))
mnt_context_get_helper_status(cxt);
