From 02b7708134037f85656d15992912226134b10250 Mon Sep 17 00:00:00 2001 From: "Reddy, Sreekanth" Date: Mon, 14 Jul 2014 12:00:49 +0530 Subject: mpt2sas: delay scsi_add_host call to work with scsi-mq In _scsih_probe, delay the call to scsi_add_host until the host has been fully set up. Otherwise, the default .can_queue value of 1 causes scsi-mq to set the block layer request queue size to its minimum size, resulting in awful performance. In _scsih_probe error handling, call mpt3sas_base_detach rather than scsi_remove_host to properly clean up in reverse order. In _scsih_remove, call scsi_remove_host earlier to clean up in reverse order.
