Re: Finally got things right... ;-) (signals & threads in LInux)

Very sane patch,IMO.  Small bug:

+int kill_posix_vm_info(int sig, struct siginfo *info, struct mm_struct* 
vm_ptr) {
+       int retval = -EINVAL;
+       if (vm_ptr != NULL) {
+               struct task_struct *p;
+
+               retval = -ESRCH;
+               read_lock(&tasklist_lock);
+               for_each_task(p) {
+                       if (p->mm == vm_ptr) {
+                               if (!sigismember(&(p->blocked), sig)) {
+                                       int err = send_sig_info(sig, info, p);
+                                       
+                                       if (retval)

                -->>            if (err)

+                                               retval = err;
+                                       break;
+                               }
+                       }
+               }
+               read_unlock(&tasklist_lock);
