This is ugly, but if sigprocmask() needs retarget_shared_pending() then handle signal should follow this logic. In theory it is newer correct to add the new signals to current->blocked, the signal handler can sleep/etc so we should notify other threads in case we block the pending signal and nobody else has TIF_SIGPENDING. Of course, this change doesn't make signals faster :/ Signed-off-by: Oleg Nesterov <oleg@redhat.com> Reviewed-by: Matt Fleming <matt.fleming@linux.intel.com> Acked-by: Tejun Heo <tj@kernel.org> |
