Oleg Nesterov f9ee228bdc signalfd: make it group-wide, fix posix-timers scheduling ... With this patch any thread can dequeue its own private signals via signalfd, even if it was created by another sub-thread. To do so, we pass "current" to dequeue_signal() if the caller is from the same thread group. This also fixes the scheduling of posix timers broken by the previous patch. If the caller doesn't belong to this thread group, we can't handle __SI_TIMER case properly anyway. Perhaps we should forbid the cross-process signalfd usage and convert ctx->tsk to ctx->sighand.
