From ffd40ef697dfd3e06f44b1bb5fea93079de8c77d Mon Sep 17 00:00:00 2001 From: Carlos Maiolino Date: Wed, 18 May 2016 11:01:00 +1000 Subject: xfs: introduce metadata IO error class Now we have the basic infrastructure, add the first error class so we can build up the infrastructure in a meaningful way. Add the metadata async write IO error class and sysfs entry, and introduce a default configuration that matches the existing "retry forever" behavior for async write metadata buffers.
