Current, when we update the 'conf' structure, when adding a drive to a linear array, we keep the old version around until the array is finally stopped, as it is not safe to free it immediately. Now that we have rcu protection on all accesses to 'conf', we can use call_rcu to free it more promptly. Signed-off-by: NeilBrown <neilb@suse.de>
