* sysdeps/unix/sysv/linux/preadv.c: The kernel API changed. Adjust.
* sysdeps/unix/sysv/linux/pwritev.c: Likewise. 2009-04-23 Jakub Jelinek <jakub@redhat.com> * sysdeps/posix/pwritev.c (PWRITEV): Fix up comment. Copy data from vector to temporary buffer and call PWRITEV after it instead of vice versa. * sysdeps/posix/preadv.c: Fix up comment. * misc/preadv.c: Likewise. * misc/preadv64.c: Likewise. * misc/pwritev.c: Likewise. * misc/pwritev64.c: Likewise. * misc/sys/uio.h (preadv, pwritev, preadv64, pwritev64): Likewise. 2009-04-23 Ulrich Drepper <drepper@redhat.com>
