The original patch is from Bart, but otherwise correct. > But he suggested it might be worth trying hpsa driver instead of cciss, > with a longer term goal to to move users of cciss over to hpsa if > possible.

And the idea behind this game is that we'd like to slowly get rid of old request_fn based drivers. Given that hpsa supports very similar hardware cciss is a target for removal once that hardware is switched over. But it seems like we'll need more work in this area.. > > -- > Meelis Roos (mr...@linux.ee) ---end quoted text---
