From 863e02d0e173bb9d8cea6861be22820b25c076cc Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Tue, 27 Oct 2015 10:49:54 +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.
