Pass this + parameter to lll_clocklock and lll_clocklock_elision in place of + CLOCK_REALTIME. (__pthread_mutex_clocklock): New function to add + LIBC_PROBE and validate clockid parameter before calling + __pthread_mutex_clocklock_common. (__pthread_mutex_timedlock): New + implementation to add LIBC_PROBE and calls + __pthread_mutex_clocklock_common passing CLOCK_REALTIME as the + clockid. + * nptl/Makefile: Add tst-mutex11.c. + * nptl/tst-abstime.c (th): Add tests for pthread_mutex_clocklock. + * nptl/tst-mutex11.c: New tests for passing invalid and unsupported + clockid parameters to pthread_mutex_clocklock. + * nptl/tst-mutex5.c (do_test_clock): Rename from do_test and take + clockid parameter to indicate which clock to be used.
