From 9a7af289660dc749d7c58234191601046a9bf488 Mon Sep 17 00:00:00 2001 From: Horst Hummel Date: Fri, 6 Jan 2006 00:19:14 -0800 Subject: [PATCH] [PATCH] s390: BIODASDPRRD ioctl return code The IOCTL BIODASDPRRD had no return code for 'profiling is inactive' and therefore tunedasd wrote misleading message for request-counter = 0. Introduce return-code EIO for inactive profiling.
