Given that ext4 also allows mounting of a cloned filesystem, the btrfs test case btrfs/312, which assesses the functionality of cloned filesystem support, can be refactored to be under the generic group. Signed-off-by: Anand Jain <anand.jain@xxxxxxxxxx> --- v3: Move back to generic v2: Move to shared testcase instead of generic. commit log updated, add _require_block_device $TEST_DEV. add _require_duplicated_fsid https://lore.kernel.org/all/440eff6d16407f12ec55df69db283ba6eb9b278c.1710599671.git.anand.jain@xxxxxxxxxx/T/#m576217a155aee49af607aa1f2aaa102ac92835e9 v1: https://lore.kernel.org/linux-btrfs/dd10c332377f315cd17abc46e08f296b87aed31c.1709970025.git.anand.jain@xxxxxxxxxx/ common/rc | 14 +++++++ tests/btrfs/312 | 78 -------------------------------------- tests/btrfs/312.out | 19 ---------- tests/generic/744 | 87 +++++++++++++++++++++++++++++++++++++++++++ tests/generic/744.out | 4 ++ 5 files changed, 105 insertions(+), 97 deletions(-) delete mode 100755 tests/btrfs/312 delete mode 100644 tests/btrfs/312.out create mode 100755 tests/generic/744 create mode 100644 tests/generic/744.out diff --git a/common/rc b/common/rc index 3ef70dfdddaa..6b9d218e3b1c 100644 --- a/common/rc +++ b/common/rc @@ -5495,6 +5495,20 @@ _random_file() { echo "$basedir/$(ls -U $basedir | shuf -n 1)" } +_require_duplicate_fsid() +{ + case "$FSTYP" in + "btrfs") + _require_btrfs_fs_feature temp_fsid + ;; + "ext4") + ;; + *) + _notrun "$FSTYP cannot support mounting with duplicate fsid" + ;; + esac +} + init_rc ################################################################################ diff --git a/tests/btrfs/312 b/tests/btrfs/312 deleted file mode 100755 index eedcf11a2308..000000000000 --- a/tests/btrfs/312 +++ /dev/null @@ -1,78 +0,0 @@ -#! /bin/bash -# SPDX-License-Identifier: GPL-2.0 -# Copyright (c) 2024 Oracle.
