__group_send_sig_info | |
do_send_sig_info | |
force_sig_info_to_task | Force a signal that the process can't ignore: if necessary* we unblock the signal and change any SIG_IGN to SIG_DFL.* Note: If we unblock the signal, we always reset it to SIG_DFL,* since we do not want to have a signal handler that was blocked |
ptrace_signal | |
kdb_send_sig | kdb_send_sig - Allows kdb to send signals without exposing* signal internals. This function checks if the required locks are* available before calling the main signal code, to avoid kdb* deadlocks. |
