From 1e7bec1f7d6533f08bc1c4ee94930c02361db86c Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 29 Jul 2024 11:05:48 -0400 Subject: btrfs: emit a warning about space cache v1 being deprecated We've been wanting to get rid of this for a while, add a message to indicate that this feature is going away and when so we can finally have a date when we're going to remove it. The output looks like this BTRFS warning (device nvme0n1): space cache v1 is being deprecated and will be removed in a future release, please use -o space_cache=v2 Reviewed-by: Qu Wenruo Reviewed-by: Neal Gompa Signed-off-by: Josef Bacik Reviewed-by: David Sterba Signed-off-by: David Sterba --- fs/btrfs/super.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'fs/btrfs/super.c') diff --git a/fs/btrfs/super.c b/fs/btrfs/super.c index 08d33cb372fb..83478deada3b 100644 --- a/fs/btrfs/super.c +++ b/fs/btrfs/super.c @@ -683,8 +683,11 @@ bool btrfs_check_options(const struct btrfs_fs_info *info, ret = false; if (!test_bit(BTRFS_FS_STATE_REMOUNTING, &info->fs_state)) { - if (btrfs_raw_test_opt(*mount_opt, SPACE_CACHE)) + if (btrfs_raw_test_opt(*mount_opt, SPACE_CACHE)) { btrfs_info(info, "disk space caching is enabled"); + btrfs_warn(info, +"space cache v1 is being deprecated and will be removed in a future release, please use -o space_cache=v2"); + } if (btrfs_raw_test_opt(*mount_opt, FREE_SPACE_TREE)) btrfs_info(info, "using free-space-tree"); } -- cgit v1.2.3-73-gaa49b
