From 41d4c60f8623d8a42f649376f678e27d802b8163 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 21 Dec 2021 08:21:28 +0100 Subject: ata: libata-scsi: rework ata_dump_status to avoid using pr_cont() pr_cont() has the problem that individual calls will be disrupted under high load, causing each call to end up on a single line and thereby mangling the output. So rework ata_dump_status() to have just one call to ata_port_warn() and avoid this problem.
