And aoeblk_gdalloc()\nis trying to acquire [3](&bdev->bd_size_lock) at set_capacity() call.\nIn this situation an attempt to acquire [4]lock(&d->lock) from\naoecmd_cfg_rsp() will lead to deadlock.\n\nSo the simplest solution is breaking lock dependency\n[2](&d->lock) -> [3](&bdev->bd_size_lock) by moving set_capacity()\noutside."
