From 6b9656205469269c050963c71fca1998b247a560 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 18 Aug 2010 11:56:59 +1000 Subject: md: provide appropriate return value for spare_active functions. md_check_recovery expects ->spare_active to return 'true' if any spares were activated, but none of them do, so the consequent change in 'degraded' is not notified through sysfs. So count the number of spares activated, subtract it from 'degraded' just once, and return it.
