Subject: [PATCH 12/18] scsi: Inline scsi_init_command()
Date: Fri, 19 May 2017 11:30:10 -0700	[thread overview]
Message-ID: <20170519183016.12646-13-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170519183016.12646-1-bart.vanassche@sandisk.com>

The two drivers that use the per-device command list, namely aacraid
and dpt_i2o, expect that that list contains only SCSI commands and
no task management functions. Hence only call scsi_add_cmd_to_list()
from the block layer prep callback functions and not from
scsi_ioctl_reset().
