From 192852be8b5fb14268c2133fe9ce5312e4745963 Mon Sep 17 00:00:00 2001 From: Carlos Maiolino Date: Wed, 18 May 2016 10:58:51 +1000 Subject: xfs: configurable error behavior via sysfs We need to be able to change the way XFS behaviours in error conditions depending on the type of underlying storage. This is necessary for handling non-traditional block devices with extended error cases, such as thin provisioned devices that can return ENOSPC as an IO error. Introduce the basic sysfs infrastructure needed to define and configure error behaviours. This is done to be generic enough to extend to configuring behaviour in other error conditions, such as ENOMEM, which also has different desired behaviours according to machine configuration.
