From 3173d8c342971a03857d8af749a3f57da7d06b57 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 4 Sep 2005 11:32:05 -0500 Subject: [SCSI] quieten messages on scsi_execute commands scsi_io_completion() can be a bit noisy about certain conditions. Previously this wasn't a problem for internally generated commands, since they never hit it. However, since we do all SCSI commands via bios, now they do. user CD testers like magicdev are now getting not ready messages every time they touch the CD to see if there's anything in it. Fix this by making all scsi_execute commands REQ_QUIET and making scsi_finish_io() not say anything for REQ_QUIET.
