  "message": "Btrfs: detect corruption when non-root leaf has zero item\n\nRight now we treat leaf which has zero item as a valid one\nbecause we could have an empty tree, that is, a root that is\nalso a leaf without any item, however, in the same case but\nwhen the leaf is not a root, we can end up with hitting the\nBUG_ON(1) in btrfs_extend_item() called by\nsetup_inline_extent_backref().\n\nThis makes us check the situation as a corruption if leaf is\nnot its own root.\n\nSigned-off-by: Liu Bo \u003cbo.li.liu@oracle.com\u003e\nReviewed-by: David Sterba \u003cdsterba@suse.com\u003e\nSigned-off-by: David Sterba \u003cdsterba@suse.com\u003e\nSigned-off-by: Chris Mason \u003cclm@fb.com\u003e\n",
