This was implemented before the change to asynchronously scan ata devices where serial discover could take inordinate amounts of time. Jack already reported a scan time reduction of 3 minutes down to 5 seconds with the async code, so I'll drop this patch. Even if recovery was taking a long time this patch would only move the hung task timeout backtrace to another location in the kernel that was dependent on the completion of error handling. -- Dan -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
