Ming Lei 52e1f85bf7 blk-mq: don't create hctx debugfs dir until q->debugfs_dir is created ... [ Upstream commit f3ec5d1155 ] blk_mq_debugfs_register_hctx() can be called by blk_mq_update_nr_hw_queues when gendisk isn't added yet, such as nvme tcp. Fixes the warning of 'debugfs: Directory 'hctx0' with parent '/' already present!' which can be observed reliably when running blktests nvme/005. Fixes: 6cfc0081b0 ("blk-mq: no need to check return value of debugfs_create functions") Reported-by: Yi Zhang <yi.zhang@redhat.com> Signed-off-by: Ming Lei <ming.lei@redhat.com> Tested-by: Yi Zhang <yi.zhang@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20220711090808.259682-1-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-08-25 11:17:36 +02:00
