From 725d6e579f06360744fc101b1af2f82d8aa282f1 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 11 Jun 2013 15:08:03 +1000 Subject: [PATCH] md/raid10: check In_sync flag in 'enough()'. It isn't really enough to check that the rdev is present, we need to also be sure that the device is still In_sync. Doing this requires using rcu_dereference to access the rdev, and holding the rcu_read_lock() to ensure the rdev doesn't disappear while we look at it.
