From 63c7c62b186f3588f4feaa7ab67911500278a17b Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Mon, 26 Oct 2015 15:54:23 +0100 Subject: [PATCH] scsi_sysfs: Fix queue_ramp_up_period return code Writing a number to /sys/bus/scsi/devices//queue_ramp_up_period returns the value of that number instead of the number of bytes written. This behavior can confuse programs expecting POSIX write() semantics. Fix this by returning the number of bytes written instead.
