nptl: Rename lll_timedlock to lll_clocklock and add clockid parameter
Rename lll_timedlock to lll_clocklock and add clockid
parameter to indicate the clock that the abstime parameter should
be measured against in preparation for adding
pthread_mutex_clocklock.
The name change mirrors the naming for the exposed pthread functions:
timed => absolute timeout measured against CLOCK_REALTIME (or clock
specified by attribute in the case of pthread_cond_timedwait.)
clock => absolute timeout measured against clock specified in preceding
parameter.
* sysdeps/nptl/lowlevellock.h (lll_clocklock): Rename from
lll_timedlock and add clockid parameter. (__lll_clocklock): Rename
from __lll_timedlock and add clockid parameter.
* sysdeps/unix/sysv/linux/sparc/lowlevellock.h (lll_clocklock):
Likewise.
* nptl/lll_timedlock_wait.c (__lll_clocklock_wait): Rename from
__lll_timedlock_wait and add clockid parameter. Use __clock_gettime
rather than __gettimeofday so that clockid can be used. This means
that conversion from struct timeval is no longer required.
* sysdeps/sparc/sparc32/lowlevellock.c (lll_clocklock_wait):
Likewise.
* sysdeps/sparc/sparc32/lll_timedlock_wait.c: Update comment to
refer to __lll_clocklock_wait rather than __lll_timedlock_wait.
* nptl/pthread_mutex_timedlock.c (lll_clocklock_elision): Rename
from lll_timedlock_elision, add clockid parameter and use
meaningful names for other parameters. (__pthread_mutex_timedlock):
Pass CLOCK_REALTIME where necessary to lll_clocklock and
lll_clocklock_elision.
* sysdeps/unix/sysv/linux/powerpc/lowlevellock.h
(lll_clocklock_elision): Rename from lll_timedlock_elision and add
clockid parameter. (__lll_clocklock_elision): Rename from
__lll_timedlock_elision and add clockid parameter.
* sysdeps/unix/sysv/linux/s390/lowlevellock.h: Likewise.
* sysdeps/unix/sysv/linux/x86/lowlevellock.h: Likewise.
* sysdeps/unix/sysv/linux/powerpc/elision-timed.c
(__lll_lock_elision): Call __lll_clocklock_elision rather than
__lll_timedlock_elision. (EXTRAARG): Add clockid parameter.
(LLL_LOCK): Likewise.
* sysdeps/unix/sysv/linux/s390/elision-timed.c: Likewise.
* sysdeps/unix/sysv/linux/x86/elision-timed.c: Likewise.
