nptl: Add POSIX-proposed pthread_mutex_clocklock
...
Add POSIX-proposed pthread_mutex_clocklock function that works like
pthread_mutex_timedlock but takes a clockid parameter to measure the
abstime parameter against.
* sysdeps/nptl/pthread.h: Add pthread_mutex_clocklock.
* nptl/DESIGN-systemtap-probes.txt: Likewise.
* nptl/pthread_mutex_timedlock.c
(__pthread_mutex_clocklock_common): Rename from
__pthread_mutex_timedlock and add clockid parameter. 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. Call
pthread_mutex_timedlock or pthread_mutex_clocklock as appropriate.
(do_test): Call do_test_clock to separately test
pthread_mutex_timedlock, pthread_mutex_clocklock(CLOCK_REALTIME)
and pthread_mutex_clocklock(CLOCK_MONOTONIC).
* nptl/tst-mutex9.c: Likewise.
