From 0213436a2cc5e4a5ca2fabfaa4d3877097f3b13f Mon Sep 17 00:00:00 2001 From: Janusz Dziemidowicz Date: Thu, 24 Jul 2014 15:48:46 +0200 Subject: scsi: do not issue SCSI RSOC command to Promise Vtrak E610f Some devices don't like REPORT SUPPORTED OPERATION CODES and will simply timeout causing sd_mod init to take a very very long time. Introduce BLIST_NO_RSOC scsi scan flag, that stops RSOC from being issued. Add it to Promise Vtrak E610f entry in scsi scan blacklist.
