[PATCH 0/5] scsi: fnic: use blk_mq_tagset_busy_iter() to walk scsi commands

[Ming Lei <ming.lei@xxxxxxxxxx>]

Hello Guys,

fnic uses the following way to walk scsi commands in failure handling,
which is obvious wrong, because caller of scsi_host_find_tag has to
guarantee that the tag is active.

        for (tag = 0; tag < fnic->fnic_max_tag_id; tag++) {
				...
                sc = scsi_host_find_tag(fnic->lport->host, tag);
				...
		}

Fix the issue by using blk_mq_tagset_busy_iter() to walk
request/scsi_command.

thanks,
Ming
