From 2b7da309ffe602d222558cee4d7e407b96e34b3a Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 20 Apr 2011 15:38:07 +1000 Subject: [PATCH] md/raid5: remove setting of ->queue_lock We previously needed to set ->queue_lock to match the raid5 device_lock so we could safely use queue_flag_* operations (e.g. for plugging). which test the ->queue_lock is in fact locked. However that need has completely gone away and is unlikely to come back to remove this now-pointless setting.
