From 5cb9b40d6127fed91b00abe44498f19f6ed6a77f 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.
