No matter how many caveats you hedge it round with, putting the API in a central place will be a bit like a honey trap for careless bears. It might be safer just to leave it buried in the three current drivers.Yeah, that was my hope but I think it would be easier to enforce to have a common function which is clearly marked legacy so that new driver writers can go look for the naming code in the existing ones, find out they're all using the same function which is marked legacy and explains what to do for newer drivers.I think I'm not the only one to be confused about the preferred direction here. James, do you agree to the approach above? It would be nice to fix virtio block for 3.4, so how about this: - I'll just apply the original bugfix patch for 3.4 - it only affects virtio
Sorry, about only affects virtio, I'm not very clear here: 1) Just duplicate the disk name format function in virtio_blk like the original patch: https://lkml.org/lkml/2012/3/28/45 2) Move the disk name format function into block core like this patch series but only affects virtio(not affect mtip32xx). Do you mean the 2) one or something else?
- Ren will repost the refactoring patch on top, and we can keep up the discussion Ren if you agree, can you make this a two patch series please?
Sure. -- Thanks, Ren _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
