Update.
2003-08-15 Ulrich Drepper <drepper@redhat.com> * io/Versions [GLIBC_2.3.3]: Add posix_fadvise64. * io/fcntl.h (posix_fadvise64): Change type of third parameter to off_t. * sysdeps/unix/sysv/linux/posix_fadvise.c: Adjust definition. * sysdeps/unix/make-syscalls.sh: Recognize V prefix to the parameter description indicating the error value is returned, not -1. * sysdeps/unix/sysv/linux/Makefile [subdir=io] (subdir_routines): Add posix_fadvise64_64. * sysdeps/unix/sysv/linux/kernel-features.h: Add definition of __ASSUME_FADVISE64_64_SYSCALL. * sysdeps/unix/sysv/linux/syscalls.list: Don't define madvise and posix_madvise in one file. Have posix_madvise defined with error value returned. Define posix_fadvise64_64 entry. Add version info to posix_fadvise64 entry. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Define posix_fadvise64_64 entry. Add version info to posix_fadvise64 entry. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/i386/posix_fadvise.S: New file. * sysdeps/unix/sysv/linux/i386/sysdep.h: Define PSEUDO_ERRVAL, PSEUDO_END_ERRVAL, and ret_ERRVAL. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * posix/Makefile (routines): Add posix_madvise. * sysdeps/generic/madvise.c: Don't define posix_madvise. * sysdeps/generic/posix_madvise.c: New file. * sysdeps/unix/sysv/aix/posix_madvise.c: New file.
