From 495d357301e1de01fabe30ce9a555301fb4675c3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 18 Jun 2009 08:49:42 +1000 Subject: [PATCH] md/linear: use call_rcu to free obsolete 'conf' structures. 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 --- Reading git-format-patch failed
