From 1bfbaf7130133ae740c09e12dfdd87df26e03d39 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 5 Feb 2021 20:13:58 +0000 Subject: linux: Consolidate fstatfs implementations The __NR_fstatfs64 syscall is supported on all architectures but aarch64, mips64, riscv64, and x86_64. And newer ABIs also uses the new fstatfs64 interface (where the struct size is used as first argument). So the default implementation now uses: 1. __NR_fstatfs64 for non-LFS call and handle overflow directly There is no need to handle __NR_fstatfs since all architectures that only support are LFS only. 2. __NR_fstatfs if defined or __NR_fstatfs64 otherwise for LFS call. Alpha is the only outlier, it is a 64-bit architecture which provides non-LFS interface and only provides __NR_fstatfs64 on newer kernels (5.1+). Checked on x86_64-linux-gnu.
