From c81d57679ee4b87a5b50e9afe4e5d1866d08b9ad Mon Sep 17 00:00:00 2001 From: Gui Hecheng Date: Thu, 5 Jun 2014 10:02:51 +0800 Subject: [PATCH] btrfs: replace EINVAL with EOPNOTSUPP for dev_replace raid56 To return EOPNOTSUPP is more user friendly than to return EINVAL, and then user-space tool will show that the dev_replace operation for raid56 is not currently supported rather than showing that there is an invalid argument.
