io,\ndon\u0027t just go directly to D_DISKLESS.\n\nWe need an additional state bit (WAS_IO_ERROR) to distinguish\nthe -\u003e D_FAILED because of IO-error from other failures.\n\nSanitize D_ATTACHING -\u003e D_FAILED to D_ATTACHING -\u003e D_DISKLESS.\nIf only attaching, ldev may be missing still, but would be referenced\nfrom within the after_state_ch for -\u003e D_FAILED,
