1. Add support for Task collector mode. 2. Fixed relative collector mode bug: - I/O failed when disks is on two ports - system hang when hotplug disk - system hang when unplug disk during run IO 3. Unlock ap->lock within .lldd_execute_task for direct mode to improve performance Signed-off-by: Xiangliang Yu <yuxiangl@marvell.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
