From b2b33e0577d3e7c8c22476021872c607173de41e Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 25 Aug 2011 14:43:53 +1000 Subject: [PATCH] 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.
