From 42e62a74377bcbb526565a31aa18da8f712b93ee Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Thu, 15 Oct 2009 17:47:11 -0700 Subject: [SCSI] zfcp: Adapt change_queue_depth for queue full tracking Adapt the change_queue_depth callback in zfcp for the new reason parameter. Simply pass each call back to the SCSI midlayer, there are no resource adjustments necessary for zfcp. Signed-off-by: Christof Schmitt Removes check for (depth <= default_depth) in case of SCSI_QDEPTH_RAMP_UP call back, not needed after added max_queue_depth per sdev.
