[PULL 11/14] file-posix: Check bs->bl.zoned for zone info |
Date: |

Instead of checking bs->wps or bs->bl.zone_size for whether zone
information is present, check bs->bl.zoned. That is the flag that
raw_refresh_zoned_limits() reliably sets to indicate zone support. If
it is set to something other than BLK_Z_NONE, other values and objects
like bs->wps and bs->bl.zone_size must be non-null/zero and valid; if it
is not, we cannot rely on their validity.
