/* Since STREAMS are not supported in the standard Linux kernel and
there we don't advertise STREAMS as supported is no need to test
the STREAMS related functions. This affects
getmsg() getpmsg() putmsg()
putpmsg()
lockf() and fcntl() are tested in tst-cancel16.
pthread_join() is tested in tst-join5.
pthread_testcancel()'s only purpose is to allow cancellation. This
is tested in several places.
sem_wait() and sem_timedwait() are checked in tst-cancel1[2345] tests.
mq_send(), mq_timedsend(), mq_receive() and mq_timedreceive() are checked
in tst-mqueue8{,x} tests.
aio_suspend() is tested in tst-cancel17.
clock_nanosleep() is tested in tst-cancel18.
Linux sendmmsg and recvmmsg are checked in tst-cancel4_1.c and
tst-cancel4_2.c respectively.
