From 21208ae5a21fd5f337e987cde11374eaf2fe70b4 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Wed, 19 Oct 2011 11:49:04 -0500 Subject: [PATCH] [SCSI] sd: remove arbitrary SD_MAX_DISKS namespace limit There is no reason to limit the SCSI disk namespace to sdXXX. Add new error messages to sd_probe() in the unlikely event that either ida_get_new() or sd_format_disk_name() fail.
