From f09e495df27d80ae77005ddb2e93df18ec24d04a Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 10 Oct 2007 16:29:02 -0400 Subject: [PATCH] usb-storage: always set the allow_restart flag This patch (as1000) sets the SCSI allow_restart flag for USB disk devices. In theory this should never hurt, and there definitely are devices out there (such as the Seagate 250-GB external drive) which need the flag to be set.
