I possibly didn't explain myself properly when saying that the rcu_read_lock needed to be taken out side of the call to which_dev. The reason was that it returns a pointer which still needs to be protected. I possibly didn't for the code as it stood, but I wanted to use call_rcu to free the old conf, so it makes sense to protect the whole usage of the structure. So I made that little change. Then added a patch to free the old conf with call_rcu. It is all now pushed out and you can see the final version of this patch at http://neil.brown.name/git?p=md;a=commitdiff;h=af11c397fd8835c70ec0bb777104e4ab98b2d660 Thanks, NeilBrown -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
