[PATCH v4 2/8] nvme: cleanup zone information initialization

Damien Le Moal
2021-01-28T04:49:51Z

For a zoned namespace, in nvme_update_ns_info(), call
nvme_update_zone_info() after executing nvme_update_disk_info() so that
the namespace queue logical and physical block size limits are set.
This allows setting the namespace queue max_zone_append_sectors limit
in nvme_update_zone_info() instead of nvme_revalidate_zones(),
simplifying this function. Also use blk_queue_set_zoned() to set the
namespace zoned model.
