From 6d56e278444bc8323b1bcfcada126b8e4dbba0f4 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 14 Apr 2009 12:01:57 +1000 Subject: md: allow setting newly added device to 'in_sync' via sysfs. When adding devices to an active array via sysfs, there is currently no way to mark a device as 'in-sync' which is useful when incrementally assembling an array. So add that option.
