ext4 and f2f2 are buggy in how they call d_invalidate, if I am reading the code correctly. d_invalidate calls detach_mounts. detach_mounts relies on setting D_CANT_MOUNT on the top level dentry to prevent races with new mounts. ext4 and f2fs (in their case insensitive code) are calling d_invalidate before dont_mount has been called to set D_CANT_MOUNT.
