Currently we have a few instances where we are generating signals setting si_code to SI_USER and si_pid to the task id. However in the case of SI_USER we are using a posix defined interface, and posix defines si_pid as the sending process id. Which in linux is equivalent to the task group id. So fix SI_USER to fill in the proper si_pid value. Signed-off-by: Eric W.
