From d8927238307b9df32319a34755ac36f6e92a0b7d Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 17 Jul 2020 09:18:39 -0300 Subject: linux: Move the struct stat{64} to struct_stat.h The common definitions are moved to a Linux generic stat.h while the struct stat{64} definition are moved to a arch-specific struct_stat.h header. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x.
