Subject: scsi: only print data direction warning once for a command
From: Andi Kleen <[EMAIL PROTECTED]>
When I use cdparanoia my logs get spammed a lot by
printk: 464 messages suppressed.
sg_write: data in/out 30576/30576 bytes for SCSI command 0xbe--guessing data in;
program cdparanoia not setting count and/or reply_len properly
printk: 1078 messages suppressed.
and many more of those. With this patch the message is only printed once
for a command in a row.
