Message-ID: <562F48C2.1070803@linux.vnet.ibm.com> Date: Tue, 27 Oct 2015 10:49:54 +0100 From: Peter Oberparleiter <oberpar@...ux.vnet.ibm.com> To: "James E.J. Bottomley" <JBottomley@...n.com> Cc: Vasu Dev <vasu.dev@...el.com>, stable@...r.kernel.org, linux-scsi@...r.kernel.org, linux-kernel@...r.kernel.org, Hannes Reinecke <hare@...e.de>, Bart Van Assche <bvanassche@....org> Subject: [RESEND PATCH] scsi_sysfs: Fix queue_ramp_up_period return code Writing a number to /sys/bus/scsi/devices/<sdev>/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.
