That's not possible, the signatures of sa_tramp and sa_sigaction do not
match:
/* union for signal handlers */
union __sigaction_u {
void (*__sa_handler)(int);
void (*__sa_sigaction)(int, struct __siginfo *, void *);
};
/* Signal vector template for Kernel user boundary */
struct __sigaction {
union __sigaction_u __sigaction_u; /* signal handler */
void (*sa_tramp)(void *, int, int, siginfo_t *, void *);
sigset_t sa_mask; /* signal mask to apply */
int sa_flags; /* see signal options below */
};
