Hi Dave & Darrick: To reproduce this problem add xfs/554 [1]. And, I resend a patch v2 [2], considering the situation mentioned by Darrick, Meanwhile, check the i_disk_size or get dir blocks at xfs_dir3_leaf_check_int looks a little strange. So in my opinion, we can just add judgment in that situation, avoiding UAF and return EFSCORRUPTED, xfs_repair will help us fix it.
