From 80268ee9270ebe4847365a7426de91d179e870d0 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 13 Oct 2008 11:55:12 +1100 Subject: [PATCH] md: Don't try to set an array to 'read-auto' if it is already in that state. 'read-auto' is a variant of 'readonly' which will switch to writable on the first write attempt. Calling do_md_stop to set the array readonly when it is already readonly returns an error. So make sure not to do that.
