In the coming btrfs-progs v5.15 release, mkfs.btrfs will change to use v2 cache by default. However nospace_cache mount option will not work with v2 cache, as it would make v2 cache out of sync with on-disk used space. So mounting a btrfs with v2 cache using "nospace_cache" will make btrfs to reject the mount. There are quite some test cases relying on nospace_cache to prevent v1 cache to take up data space. For those test cases, we no longer need the "nospace_cache" mount option if the filesystem is already using v2 cache. Since v2 cache is using metadata space, it will no longer take up data space, thus no extra mount options for those test cases. By this, we can keep those existing tests to run without problem for both v1 and v2 cache. Signed-off-by: Qu Wenruo <wqu@suse.com> --- Changelog: v2: - Introduce a new helper _scratch_no_v1_cache_opt() to generate needed mount option By this, it could be more future proof for extent-tree-v2 --- common/btrfs | 9 +++++++++ tests/btrfs/102 | 2 +- tests/btrfs/140 | 5 ++--- tests/btrfs/141 | 5 ++--- tests/btrfs/142 | 5 ++--- tests/btrfs/143 | 5 ++--- tests/btrfs/151 | 4 ++-- tests/btrfs/157 | 7 +++---- tests/btrfs/158 | 7 +++---- tests/btrfs/170 | 4 ++-- tests/btrfs/199 | 4 ++-- tests/btrfs/215 | 2 +- 12 files changed, 31 insertions(+), 28 deletions(-)
