md/raid5: ensure we create a unique name for kmem_cache when mddev has no gendisk We will shortly allow md devices with no gendisk (they are attached to a dm-target instead). That will cause mdname() to return 'mdX'. There is one place where mdname really needs to be unique: when creating the name for a slab cache. So in that case, if there is no gendisk, you the address of the mddev formatted in HEX to provide a unique name. Signed-off-by: NeilBrown <neilb@suse.de>
