No, that's wrong. I got Ingo to remove this code and he documented it: ===== - race fix: do not bail out in the list walk when the list_op_pending pointer cannot be followed by the kernel - another userspace thread may have already destroyed the mutex (and unmapped it), before this thread had a chance to clear the field. ===== - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
