* sysdeps/unix/sysv/linux/i386/Makefile: New file.
Wed Apr 24 17:35:30 Ulrich Drepper <drepper@cygnus.com>
* inet/netinet/in.h, socket/sys/socket.h: Move to
sysdeps/generic/netinet/in.h, sysdeps/generic/sys/socket.h.
* netinet/in.h, sys/socket.h: Remove file.
* misc/Makefile (routines): Add fdatasync.
* posix/Makefile (headers): Add sched.h.
(routines): Add nanosleep, sched_setp, sched_getp, sched_sets,
sched_gets, sched_yield, sched_primax, sched_primin, sched_rr_gi.
* posix/getconf.c (vars): Add entries for _POSIX_REALTIME_SIGNALS,
_POSIX_PRIORITY_SCHEDULING, _POSIX_TIMERS, _POSIX_ASYNCHRONOUS_IO,
_POSIX_PRIORITIZED_IO, _POSIX_SYNCHRONIZED_IO, _POSIX_FSYNC,
_POSIX_MAPPED_FILES, _POSIX_MEMLOCK, _POSIX_MEMLOCK_RANGE,
_POSIX_MEMORY_PROTECTION, _POSIX_MESSAGE_PASSING,
_POSIX_SEMAPHORES, _POSIX_SHARED_MEMORY_OBJECTS.
* posix/sched.h: New file. Header for POSIX scheduling interface.
* posix/unistd.h: Describe options from POSIX.4.
Add declaration of fdatasync.
* sysdeps/generic/confname.h: Add definition for
_SC_REALTIME_SIGNALS, _SC_PRIORITY_SCHEDULING, _SC_TIMERS,
_SC_ASYNCHRONOUS_IO, _SC_PRIORITIZED_IO, _SC_SYNCHRONIZED_IO,
_SC_FSYNC, _SC_MAPPED_FILES, _SC_MEMLOCK, _SC_MEMLOCK_RANGE,
_SC_MEMORY_PROTECTION, _SC_MESSAGE_PASSING,
_SC_SEMAPHORES, _SC_SHARED_MEMORY_OBJECTS.
* sysdeps/generic/fdatasync.c: New file. Default implementation
simply uses fsync.
* sysdeps/generic/netinit/in.h: Moved to here from inet/netinet/in.h.
* sysdeps/generic/schedbits.h: New file. System dependent
defintion for POSIX.4 scheduling interface.
* sysdeps/generic/sys/socket.h: Moved to here from socket/sys/socket.h.
* sysdeps/stub/nanosleep.c, sysdeps/stub/sched_getp.c,
sysdeps/stub/sched_gets.c, sysdeps/stub/sched_primax.c,
sysdeps/stub/sched_primin.c, sysdeps/stub/sched_rr_gi.c,
sysdeps/stub/sched_setp.c, sysdeps/stub/sched_sets.c,
sysdeps/stub/sched_yield.c: New file: Stub implementation
for systems missing these POSIX.4 system calls.
* sysdeps/unix/sysv/linux/gnu/types.h,
sysdeps/unix/sysv/linux/ioctls.h: Use kernel header for
data type definitions.
* sysdeps/unix/sysv/linux/netinet/in.h: New file. Linux
specific version.
* sysdeps/unix/sysv/linux/posix_opt.h: New file. Define POSIX
options applicable for Linux.
* sysdeps/unix/sysv/linux/syscalls.list: Add definitions for
fdatasync, nanosleep, sched_setparam, sched_getparam,
sched_setscheduler, sched_getscheduler, sched_yield,
sched_get_priority_max, sched_get_priority_min, and
sched_rr_get_interval.
* sysdeps/unix/sysv/linux/sysconf.c: Add handling of POSIX.4
options.
* sysdeps/unix/sysv/linux/termbits.h: Use kernel headers.
* time/sys/time.h: Remove definition of `struct timespec'.
* time/time.h (struct timespec): Move definition to here.
