From 8ed0a5216a0238f53b482ec88ce4aeed4b9f0da1 Mon Sep 17 00:00:00 2001 From: Neil Brown Date: Sat, 28 Jun 2008 08:31:29 +1000 Subject: [PATCH] Enable setting of 'offset' and 'size' of a hot-added spare. offset_store and rdev_size_store allow control of the region of a device which is to be using in an md/raid array. They only allow these values to be set when an array is being assembled, as changing them on an active array could be dangerous. However when adding a spare device to an array, we might need to set the offset and size before starting recovery. So allow these values to be set also if "->raid_disk < 0" which indicates that the device is still a spare.
