Appended patch looks good to me, Reviewed-by: Christian Brauner <brauner@xxxxxxxxxx> The patch also has another fix for O_EXCL. In earlier versions of this patch series it relied of f_flags. Thanks for that comment you added in there about this now. This really helps given that O_EXCL has special meaning for block devices. Ideally we'd have kernel doc for file_to_blk_mode().
