From 745e967a49b26725cc9f30105ff67c8fee8926d6 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 6 Sep 2012 17:35:00 +0200 Subject: [PATCH] s390/vmlogrdr: change return value from -ENOSYS to -EOPNOTSUPP Changing the return value of vmlogrdr_open() to -EOPNOTSUPP if O_NONBLOCK is specified shouldn't have any negative side effects. Any existing user wouldn't specify that flag since it wouldn't work anyway.
