I do not think it does:
static int blk_validate_zoned_limits(struct queue_limits *lim)
{
if (!lim->zoned) {
if (WARN_ON_ONCE(lim->max_open_zones) ||
WARN_ON_ONCE(lim->max_active_zones) ||
WARN_ON_ONCE(lim->zone_write_granularity) ||
WARN_ON_ONCE(lim->max_zone_append_sectors))
return -EINVAL;
return 0;
}
...
So setting lim->zoned to false without clearing the other limits potentially
will trigger warnings...
