From 1fbd84bf6887243f51b2ad95241a183ce547aea5 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 18 Nov 2024 14:33:53 +0100 Subject: [PATCH] [3.13] gh-126909: Fix running xattr tests on systems with lower limits (GH-126930) (#126965) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gh-126909: Fix running xattr tests on systems with lower limits (GH-126930) Modify the extended attribute tests to write fewer and smaller extended attributes, in order to fit within filesystems with total xattr limit of 1 KiB (e.g. ext4 with 1 KiB blocks). Previously, the test would write over 2 KiB, making it fail with ENOSPC on such systems.
