From f53e29fc87b6fb76db0043202ec2c3450caa5ff3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 13 Feb 2012 14:24:05 +1100 Subject: [PATCH] md/raid1: fix buglet in md_raid1_contested. Since we added 'replacement' capability, RAID1 can have twice as many devices as ->raid_disks indicates. So md_raid1_congested needs to check that many possible devices, not just ->raid_disks many.
