    target: Drop se_device TCQ queue_depth usage from I/O path · 65586d51
    Nicholas Bellinger authored
    Historically, pSCSI devices have been the ones that required target-core
    to enforce a per se_device->depth_left.  This patch changes target-core
    to no longer (by default) enforce a per se_device->depth_left or sleep in
    transport_tcq_window_closed() when we out of queue slots for all backend
    export cases.
