Don't you need this bit as well?

+ sigemptyset(&sigign);
+ sigemptyset(&sigcatch);

to replace this bit from your previous patch.

static void collect_sigign_sigcatch(struct task_struct *p, sigset_t *ign,
sigset_t *catch)
struct k_sigaction *k;
int i;

- sigemptyset(ign);
- sigemptyset(catch);

That was in the patch I sent you ... but I missed task->sighand->siglock ;-)
