    Subject[PATCH 4.19 159/280] scsi: aacraid: Fix performance issue on logical drives
    Date
    4.19-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Sagar Biradar <sagar.biradar@microchip.com>

    commit 0015437cc046e5ec2b57b00ff8312b8d432eac7c upstream.

    Fix performance issue where the queue depth for SmartIOC logical volumes is
    set to 1, and allow the usual logical volume code to be executed

    Fixes: a052865fe287 (aacraid: Set correct Queue Depth for HBA1000 RAW disks)
