From 07d5035a289f8bebe0ea86c293b2d5412478c481 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 17 Apr 2014 08:15:27 +1000 Subject: [PATCH] xfs: wrong error sign conversion during failed DIO writes We negate the error value being returned from a generic function incorrectly. The code path that it is running in returned negative errors, so there is no need to negate it to get the correct error signs here. This was uncovered by generic/019.
