null_blk: suppress invalid partition info
null_blk is partitionable, but it doesn't store any of the info. When it is loaded, you would normally see: [1226739.343608] nullb0: unknown partition table [1226739.343746] nullb1: unknown partition table which can confuse some people. Add the appropriate gendisk flag to suppress this info. Signed-off-by: Jens Axboe <axboe@fb.com>
