From 30f1c7439489bf756a45e349d69be1826e0c9bd8 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 17 Jul 2020 13:15:37 -0300 Subject: linux: Implement {l}fstat{at} in terms of fstatat Both fstatat and fstata64 calls the old fxstatat and fxstatat64 repectivelly with _STAT_VER, the one currently exported as default for all ABIs. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.
