zbd: only put an upper limit on max open zones once
There is an upper limit that is checked for each td, and for each file, even though a file has a pointer to a zoned_block_device_info that has already been created. Multiple files, from the same or from another td can point to the same zoned_block_device_info. All zoned_block_device_info:s have already been created earlier in the call chain. Simplify this by only checking the upper limit on max open zones when a zoned_block_device_info is created. This way, max_open_zones is handled from a single location, instead of potentially being reassigned from a completely different location. Signed-off-by: Niklas Cassel <> Signed-off-by: Jens Axboe <>
