md/linear: avoid corrupting structure while waiting for rcu_free to complete.
commit 1b6afa17581027218088a18a9ceda600e0ddba7a upstream. I don't know what I was thinking putting 'rcu' after a dynamically sized array! The array could still be in use when we call rcu_free() (That is the point) so we mustn't corrupt it. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
