Hi! Apparently fchownat was only changed to use the direct syscall if available in the generic linux version, not in the various arch specializations. 2006-08-08 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/s390/s390-32/fchownat.c (fchownat): Use fchownat syscall if available. * sysdeps/unix/sysv/linux/powerpc/fchownat.c (fchownat): Likewise. * sysdeps/unix/sysv/linux/sh/fchownat.c (fchownat): Likewise. * sysdeps/unix/sysv/linux/i386/fchownat.c (fchownat): Likewise. --- libc/sysdeps/unix/sysv/linux/s390/s390-32/fchownat.c.jj 2006-01-11 16:55:32.000000000 +0100 +++ libc/sysdeps/unix/sysv/linux/s390/s390-32/fchownat.c 2006-08-08 11:11:23.000000000 +0200 @@ -53,6 +53,24 @@ extern int __libc_missing_32bit_uids;
