*	nptl: pthread_kill needs to return ESRCH for old programs (bug 19193)	Florian Weimer	2021-09-20	1	-2/+19
\| \| \| \| \| \|	The fix for bug 19193 breaks some old applications which appear to use pthread_kill to probe if a thread is still running, something that is not supported by POSIX.
*	nptl: pthread_kill, pthread_cancel should not fail after exit (bug 19193)	Florian Weimer	2021-09-13	1	-0/+46
	This closes one remaining race condition related to bug 12889: if the thread already exited on the kernel side, returning ESRCH is not correct because that error is reserved for the thread IDs (pthread_t values) whose lifetime has ended. In case of a kernel-side exit and a valid thread ID, no signal needs to be sent and cancellation does not have an effect, so just return 0. sysdeps/pthread/tst-kill4.c triggers undefined behavior and is removed with this commit.
