Perhaps it should simply do that: if you would choose P to oom-kill, and P->mm->core_state!=NULL, then choose P->mm->core_state->dumper instead. > Well, we can use TIF_MEMDIE if we chose the right thread, I think. > But perhaps mm->flags |= MMF_OOM is better, it can have other user. > I dunno. This is all the quick hack before get around to just making core dumping fully-interruptible, no? So we should go with whatever is the simplest change now. Perhaps this belongs in another thread as you suggested. But I wonder what we might get just from s/TASK_UNINTERRUPTIBLE/TASK_KILLABLE/ in exit_mm.
