[PATCH] wrong pid in siginfo_t
If a signal is sent via kill() or tkill() the kernel fills in the wrong
PID value in the siginfo_t structure (obviously only if the handler has
SA_SIGINFO set).
POSIX specifies the the si_pid field is filled with the process ID, and
in Linux parlance that's the "thread group" ID, not the thread ID.
