2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: NeilBrown commit 80268ee9270ebe4847365a7426de91d179e870d0 upstream. '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.
