poky/meta/recipes-extended/ltp/ltp/0001-testcases-Fix-largefile-support.patch

From 3cca69b85c88c6eb4f02313b3c6a9e0f6cc0b5d7 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Wed, 14 Dec 2022 18:14:22 -0800
Subject: [PATCH] testcases: Fix largefile support

Use standard functions ( not 64-bit equivalents ) which operate on off_t
and pass -D_FILE_OFFSET_BITS=64 to enable LFS always so off_t is 64bit
for these tests.

This helps making it portable across musl which has removed the 64bit
transition functions from _GNU_SOURCE namespace.

Upstream-Status: Submitted [https://lists.linux.it/pipermail/ltp/2022-December/032310.html]
