-Subject: btrfs: compare the correct fsid/metadata_uuid in btrfs_validate_super
-
-From: Anand Jain <anand.jain@oracle.com>
-
-commit 6bfe3959b0e7a526f5c64747801a8613f002f05a upstream.
-
-The function btrfs_validate_super() should verify the metadata_uuid in
-the provided superblock argument. Because, all its callers expect it to
-do that.
-
-Such as in the following stacks:
-
- write_all_supers()
- sb = fs_info->super_for_commit;
- btrfs_validate_write_super(.., sb)
- btrfs_validate_super(.., sb, ..)
-
- scrub_one_super()
- btrfs_validate_super(.., sb, ..)
-
-And
- check_dev_super()
- btrfs_validate_super(.., sb, ..)
-
-However, it currently verifies the fs_info::super_copy::metadata_uuid
-instead. Fix this using the correct metadata_uuid in the superblock
-argument.
